I found same issue today was playing this morning then 'poof' won't let me in and no longer compatible. I've been playing now for a couple months have gotten pretty far. I play daily. I'm very sad about this and hope it's fixable. I had food cooking and was very close to completing goals. I play restaurant story, bakery, fashion, dragon, castle, and farm 2, as well as bingo and candy manias. I fully understand glitches for new game formats and glady tolerated the laggy glitches but to let me get so far then take it away is cruel.
I hope a fix is posted quickly!
