Ensure you're using the most recent version of Bonza by downloading any updates from the App Store.
Low storage can cause issues with Bonza, we recommend leaving at least 1gb free. To check, go into your device settings, tap on “General” and then navigate to “Usage”. Try deleting some unnecessary data (we suggest moving photos to your computer, or removing unused apps).
Ensure that you’re logged into iCloud on your device/s. Do this from the "iCloud" section of your device settings. You should also check to make sure you have available storage on your account. You may need to sign out of iCloud then sign back in on your device/s.
Go to the Bonza Settings page (the little cog in the top corner of the Bonza title screen). Scroll down and tap "Restore purchases". This should unlock any packs purchased with your account.
If you still don’t see your progress restored, send an email to email@example.com tell us roughly where you were up to and how many coins you had. We will get back to you as soon as we can.
