760 broke the slide open little windows after a battle. You can't tap them anymore. They used to take you to collect the reward screen. Now nothing. Example. Do 5 classic arena. You do this. Before 760 it used to slide open telling you  you've done it and you can tap it and it takes you to collect the reward. Notes none of these tote  types of windows work. Tap does nothing. 

it's on android and iOS all accounts. Must be fixed.
