Licenses issues and solutions

There are a few different types of Unlocker that enable all application options in Yatse.
Whichever one has been purchased, your license is a permanent one and there's never any need to buy a new one to keep the same level of functions.

Identify the type of Unlocker you have bought:
Google Play Store In-App: This is the most common type of Unlocker if you bought Yatse after July 2014. It appears on your Google wallet as: Yatse Unlocker (Yatse: XXX)
Google Play Store Legacy Unlocker: This unlocker was used as an external application when Yatse was first created. It's still supported but should no longer be purchased for new users. You probably have this unlocker if you purchased it a very long time ago. (It appears on your Google wallet as just: Yatse Unlocker)
Amazon Store In-App: This is the only unlocker that was available on Amazon store, until Amazon removes Yatse.
Paypal Unlocker: This is the unlocker bought from our website when you do not trust Google Play Store. It is however recommended that you use the Google Play Store In-App for both ease of use and a little lower price.

Then look at the dedicated section:

Known problems (general):
• Titanium backup restored license information can be incorrectly detected as an attempted license hack. Please ensure that you re-install Yatse from the Play Store each time to resolve this. We recommend that if you need to re-install Yatse, to use the built in Yatse Cloud Save feature to save and restore your application settings.
• The Play Store needs your phone to have a correct date, time and time zone. Be sure to have those set correctly.

Known In App problems:
Lucky Patcher breaks Play Store licenses checks, so please disable all In App emulation functions if Yatse is telling you that the In App purchase is not ready. (Uninstall is not enough!)
• If you have a not so legit Unlocker apk on your phone you will need to uninstall it and then clear the Yatse application data (or uninstall then reinstall Yatse)
• Yatse In App performs a licenses check over the internet on a regular basis when launched. Currently Ad Block Plus prevents this check from working. You will need to disable ad block if the license invalidates so it can validate itself once again.
• Check that Yatse has internet access and can access http://genimee.com/. Ensure that this is not blocked by any other security tool or firewall.
• If you have multiple accounts on your device, please be sure to install Yatse with the account associated with the in-app purchase. The easiest way is to uninstall Yatse from your device and then push the re-install from the web based Google Play Store on a computer when logged with the correct account.
• If you have just bought Unlocker via the In App option, it can take a couple of hours to be available on all your devices. This is due to how Google replicate and validate the licenses over multiple devices. Just wait a little time. If you go to the buy screen and validate that it says already bought then reboot the device.
• You need to have data sync enabled for the Google account you made the purchase. (Android settings / Accounts / Google / App data sync)

Known problems (general):
• Titanium backup restored license information can be incorrectly detected as an attempted license hack. Please ensure that you re-install Yatse from the Play Store each time to resolve this. We recommend that if you need to re-install Yatse, to use the built in Yatse Cloud Save feature to save and restore your application settings.
• The Play Store needs your phone to have a correct date, time and time zone. Be sure to have those set correctly.

Known Legacy Unlocker problems:
Lucky Patcher breaks Play Store licenses checks, so please disable all In App emulation functions if Yatse is telling you that the In App purchase is not ready. (Uninstall is not enough!)
• The Google Play Store has some problems with multiple accounts and license checks. Please be sure to install the Legacy Unlocker with the account associated with the app purchase. The easiest way is to uninstall the Unlocker from your device and then push the re-install from the web based Google Play Store on a computer when logged with the correct account.
xPrivacy can break the Legacy unlocker license verification if you remove some permissions.
Play Store cache corruption, can some times occur and invalidate the license. If this happens, uninstall both Yatse and the Legacy unlocker applications, clear the Play Store cache then install them once again. (Again, consider using the Yatse Cloud Save feature for easy saving and restoration of your hosts and settings).

Known Amazon In App problems:
• If you have a not so legit Unlocker apk on your phone you will need to uninstall it and then clear the Yatse application data (or uninstall then reinstall Yatse)
• You cannot install Yatse from Play Store then update to Amazon version. You need to do a fresh install from Amazon or Amazon In App will not detect the purchase.
• You cannot update Yatse from Play Store when you purchased on Amazon.

Remark:
Yatse is not more distributed and updated on Amazon store as Amazon decided to remove Yatse from their store without any explanation. There is nothing we can do about that as it's an unilateral decision.

Known problems (general):
• Titanium backup restored license information can be incorrectly detected as an attempted license hack. Please ensure that you re-install Yatse from the Play Store each time to resolve this. We recommend that if you need to re-install Yatse, to use the built in Yatse Cloud Save feature to save and restore your application settings.

Known Paypal problems: (Purchased from the Website, not the Paypal app in Google Play)
• When you buy Paypal Unlocker, you register it for a specific mail account. This account needs to be on your device for license validation. This account can not be changed later!
• You need to have the purchased Unlocker installed on your device.
• You need to allow the Unlocker permission to read accounts on your device.
• If you have lost your Unlocker, you can just enter your mail again in the purchase dialog box. You'll be sent the details again by email. (Website)
• If Google changed your mail from @gmail.com to @googlemail.com or vice versa you can revert this change back by following: Google FAQ

Licences are handled by Google and Amazon.
There's no way to transfer licences from Amazon to Google or the opposite.
Google does not allow transferring licences from an account to another, but Amazon support seems more open to that kind of changes.

If you still have problems after reading and applying all the above points, please contact us for help with:
• Your details about each of the points corresponding to your unlocker type.
• Logs (Debug logs).
• Your Order Number (mail from Paypal, Amazon, Google or listed at Google Payments).
To have more details when gathering logs, please click on the purchase Unlocker again to get the error message!

Remarks:
• You can access your order history at Google Payments if you have lost the purchasing email.
• Yatse supports multiple kinds of Unlockers that work differently depending on where and when your made your purchase, but all provides the same functions.
• Licenses purchased on the Google Play Store are tied to your Google account, so will work on any device using the same account.
• If you bought the unlocker as a separate Google Play app (Legacy Unlocker), you'll need to continue to use it as there's no way to transfer the license to In App license.
• Legacy Unlocker unlocks exactly the same features and will continue to be supported for previous buyers. You just need to continue to install Legacy Unlocker when you change your phone or reset it.
