I see, sorry. Maybe someone else will chime in when my message bumps this doscussion to the top of the front page. I couldn't find anyone else mentioning this app with the search function.
In the interim, it'd help to have more info on what you're experiencing/seeing. Does "play integrity API" notification pop up?
Does the app say error or close itself and back to your home screen?
The log file should pinpoint the issue:
Going to the apps info page (hold your finger down on its icon, a menu pops up for app info). Then there's view logs.
'App compatibility mode' in this menu might help. Or turning off secure app spawning or mte. Temporarily as a test.
Goodluck, TSA lines are very long.
