I didn't receive my Invitation Event reward!

I was about to receive the last Daily Gift, but the reward list has been reset.

I can't update my game on iOS.

I pressed "Next Combi" in Breakout, and then my Mystery Boxes disappeared!

When I open the game, it keeps telling me that I'm currently logged under another account.

I want to link my account to a second device, but the link code does not appear.
