John564479 I have had issues with some google play apps not working due to these api verification checks. I turned off network access to google play and now it all seem to work again. I just wanted to share this potential fix
fid02 John564479 You should be able to achieve the same by simply blocking the apps from using the API. You can enable network access for Play again and then go to Settings > Apps > app in question > Play Integrity API > enable Block usage attempts
