Solution: Clear all data from the Google Play Store app. You will not lose any purchased apps or games; this simply cleans up the local copy of the data, and Google Play will download everything again when you restart it. This is unfortunately a long-standing well-known bug in Google Play. It’s not something we can fix in our app (trust us, we’ve tried a lot!)
If you have multiple Google Accounts set up on your device, then Google Play does not always correctly associate your in-app purchases with the right account.
This is another bug in Google Play, not this app, and affects many more apps. See discussions here, here, and here.
Follow the same steps as above for a work-around.
