all my worlds are gone

Good day. I don't speak English, I hope the translation works. All my saved games have been gone for a good 3 days, all worlds have disappeared, I can't play anymore since the last update!

I can still find all the packages I have bought under Settings, but I always get the message I should buy the game. I bought the game a long time ago and now I want to be able to play normally. I am very angry!
