If you are having issues with your paid features or paid content not unlocking automatically, please try the following tips:
1. Make sure you are logged in to the Google Play Store with the same Google account you made your purchase on. This is important because all transactions in the app are linked to your Google Play Store account.
2. Do you happen to have multiple Google Play Store accounts on our phone? If so, please try logging out of the other ones and only stay logged into the one you have your purchase under. Being logged into multiple accounts can cause errors with the Google Play Store.
3. You can also try deleting the app and reinstalling a fresh version from the Google Play Store.
