After opening the game, it says loading for about a second then the error message pops up. Can't do anything after that other than quit out the game and try again.
I have tried opening the game and it works perfectly for me. Can you re-download the game and try again? Maybe you're playing a version that had a bug that I've already fixed.
I re-downloaded the game but I got the same error message. I think it's just my phone being cheap and old because some other games also don't work on it.
