Android 12 has been out over a year now and the lack of a "domain" field in the WiFi profile for an EAP WiFi profile is still preventing our Android devices from being able to join these WiFi networks. When I created a support request for this last year I was told this was part covered by AAGNT-192575. While it wasn't mentioned in the release notes, I recently upgraded to 2203.20 thinking that this might have been resolved but nope, that field is still missing.
As a point of reference, Microsoft has this field available on Intune for Android WiFi profiles and Android 12 phones enrolled in Intune are able to join our company WiFi.
