dregrinfuces I'm assuming I'd want to turn off the checks for Play Integrity in the USAA "Per App Play Integrity Menu" in case the app decides it isn't going to run on GOS.
The only benefit of doing this right now (when the app works) is that it might eliminate the annoying messages. OTOH, it might actually cause the app to refuse to run.
The main reason to disable the checks is that in some cases it might allow an app to run that otherwise wouldn't. The result of disabling checks will depend entirely on how the app is coded.
