A client came to fix his phone because it is receiving this message when he opens the recently installed "McDonald's" app:

Your device did not pass our security check. Please check that you run a Google trusted OS version, that the device is not rooted and that you have no harmful apps installed

Curiously the phone is not rooted, and is also a modern and updated Samsung phone.

What could be the issue? solutions?

Try to run a safety net test on the device. Check if they have a custom recovery, or if the bootloader is unlocked. If it is Samsung, check if Knox is triggered. How do you know it is not rooted? In what way did you check?
