========================================
After the recent system update to Android 10, I received notification to update and I did it. After the update, rebooting the phone I am not getting network, sim is disabled. Please see screenshot.
I have removed the sim and inserted back, still the sim is disabled. I am unable to use phone for calling.
Expected a better tested version from Asus. Totally disappointed. How do i revert back to Android 9?
