What you were expecting to happen, and what actually happened:
I have already rated Gems on Google and I keep getting popups to rate. Expected to no longer get the popup asking me to rate.
How often does this happen? When did it begin happening?
Was this a once-off bug or has it been a consistent issue? Does it only happen after doing a particular game mode?
Constantly, since the update.
Steps to make it happen again
Play the game, popup occurs randomly.
I rated gems earlier this month. I am logged into Google play games using the same email as Gems. My hubby rated Gems and received a small reward, I have not (not concerned about that) and he has not gotten any more popups thus far. I rated the game through the popup screen. I have tried to edit my rating to see if Gems would see that I have already rated the game, did not work. I have completely closed game and still get popup.
