Hi!
I just wanted to share a solution for bypassing Google Play Protect problem when installing your apps.
We had this problem for one of our apps but we came up with the following workaround:
Create an Application Run Control profile and set it to blacklist: com.android.vending (Which is the Google Play store)
Also create a Feature Control profile with the setting for "Disable Verify Apps Enforcement" ticked.
Have the Application Run Control profile assigned to the devices as long as they don't have the correct version/not even installed of the app which are getting blocked all the time.
So far this seems to work but we can't really tell if the app gets totally blacklisted in the future which will make Play Protect to actually delete the app but I have not heard of anything like that before.
