Timed tavern coins aren't showing in bag despite winning them in beach tiles event, is anybody else..

Did you complete the entire stage of the beach tiles game? When you complete the opening easy section the game looks like its giving you rewards, but it is just teasing the possible total rewards you can get from completing the whole game.

If you have actually found all of the tiles in the main stage of the game then you should have received some Tavern coins. I would suggest contacting support using the customer service via the help section in settings.
