Yes, apparently the user interface has changed and the past method of claiming the coins doesn't work anymore. I am getting the red dot indicating there is action to be taken
1) on the gift box at the top of the home page, then when clicked...
2) on the "Today's Gifts yellow box on the events page, then when clicked...
3) on the Daily Column on the Mission Possible page.
Or going from the Profile page, there is a red dot on rewards that when clicked will take me to the Mission Possible page.
But on that page, there is no "Claim" button or line to get my normal 10 coins. There is no action to be taken anywhere there.
I can get the coins by going to the Profile page, and then Clicking on the Membership ad and then clicking on the Claim button there. It evidently is now a daily claim button rather than a try to subscribe button like it was previously.
Once I do that, I get my 10 coins rewarded, and in the rest of the app interface, all the red dots disappear.
Definitely a bug. If nothing else, having the red dots appear with no possible actions is a bug. But I believe the real bug is the Claim coins line in the daily mission disappearing.
