Got the new update now when I go to the tower and click challenge, the screen freezes. It doesn't continue. I exit out lf the game go back and nothing changes. And it's not my network connection I'm not using Wifi. It's been a year and it's still the same! Edit: The freeze happens when I go the wizard tower and I click challenge. Then the characters go away then nothing. I am left on that screen and I cand go back unless I fully exit out of the game. Just tried airplane mode it worked.
