I have encountered this too and now I can not continue playing my game! This is very frustrating.
Device: Samsung Galaxy S7 (SAMSUNG-SM-G930V)
OS: Android 6.0.1
Team: Barbarian, Wizard, Paladin, Rogue, Sorcerer, Cleric
Observations: Sound cues for actions plays but game does not respond (IE Selecting Settings, Selecting Roles button, Selecting (grayed out) Next Arrow)
I have tested this starting from each character and as soon as I select the next character the game stops responding (except the audio sounds for selecting buttons). Closing the app and reopening, then continuing takes me to the Victory screen and I collect the reward cards with no issues. When I go to the next screen it pops up with the initial Roles notification offering to view the rules or continue (I have done both). After continuing past that the game pops up with the Roles notification for the character with an arrow pointing to the Roles icon. Note that I cannot select Settings at any point during this process after I finish with the reward cards and until I select a Role to view the abilities, though it still makes the sounds for selecting the settings icon. Otherwise, the game is still completely responsive UNTIL I finish with the first character's Role, including being able to navigate between the tabs (Skills, Powers, Cards List, and Completion). As soon as I select the second character the Roles notification with the arrow pops up and the game stops responding, the settings button also non-responsive. I have even turned Tips off and it still did not fix the issue. Neither does switching between Phone and Tablet interfaces or rotating the screen.
