We've heard from some players that after updating to v45, they receive an error on app startup that blocks them from entering the game. 

The team has just solved this issue via an update in our backend. To get the fix, please completely close and restart your game. 

Thanks very much for your patience as we investigated this issue! ❤️ If you continue to have any trouble with the game, please let us know so that we can help get you back on track!
