I haven't been getting notifications for Crypts, Fishing, Training..etc. They were working earlier today, but the last couple of times I had to manually check those games and training.

I am having the same problem.

You may play again in -241 min. -59 sec.

I haven't been getting them for Scratchcards or Random.

I just got a bunch of notifications all at once, so we'll see if they start working properly soon.
