We have released the 51.00 update for iOS and Android.

For iOS Players, you should be able to go to the App Store and update Frozen Adventures
For Android / Google Play, it is currently on phased release, some players will be able to update to the 51.00 version. If the update is not available, it will be available to all players within the next week.

We hope that this resolves your issue. If the issue still persists on the 51.00 update, please let us know!
