Fun game but there is one issue – Kung Fu Clicker: Idle Dojo Review

This is a great game but the free ways to get gems by playing other games is very buggy, I just completed one of the goals to get 1200 gems, and when I went back to the game it was a black screen. So I reopened the app and I never got my gems, if I didn’t do it correctly then please give instructions on how to do it right, thanks.
