Unable to exit selected spell
I experienced this issue during the tutorial and thought it stopped after that. It still happens from time to time in the game as well.
Once I select a spell from the spell list, I am not given any way to exit. I have to restart the game or buy the spell.
I had the same issue, works fine before. But after reaching level 5, I want to read some spell description to know the detail, but there is no exit or back button. I have to buy the spell or exit the game to solve this.
My Device is Xiaomi Mi 5, running on Android 7.0
This also happened to me at the beginning of the game on the tutorial I think. After it's ok.
