Today I played dungeon battles on my mobile phone (Samsung S7 Edge if that matters) and after each victory the game would freeze. My screen would look like this
I couldn’t do anything after this except to get out of the game altogether. When I would get back, I would get a victory, but I don’t know if I received any of the rewards. I did all three battles because I wanted to see if this would repeat and yes it did repeat after all dungeon battles. Please look at this issue.
