I am having a similar issue that I only encountered once I updated my physical device to 14.3. ATTrackingManager.trackingAuthorizationStatus always returns .denied: I've verified that Settings > Privacy > Tracking > Allow Apps to Request to Track is enabled
Under Settings > Privacy > Tracking, there is no entry for my app to toggle individual app permissions on or off
Uninstalling and reinstalling app has no effect on status
Rebooting device has no effect
I have a separate device that has 14.4 beta 2 installed. This device behaves as expected (uninstalling and reinstalling app correctly resets permission to .notDetermined)
tonioquellovero, are you running 14.3 as well?
Update. Similar issues here:

As far as I can tell, this appears to be an iOS 14.3 issue. I did not have this issue before updating to iOS 14.3, and I do not have this issue on 14.4 beta 2.
