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).
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 packs, send an email to firstname.lastname@example.org tell us which packs you are missing and we will get back to you as soon as we can.
