hi,
I have a
Fairphone 4
UT 24.04 1.1
Germany
Fonic (Telefonica, O2)
overall its working pretty good. I have a more stable phone call connection with better quality because before the last update only 2G worked for me.
a nice additional benefit for me is the gain in battery life while staying on 4G all day long 
VoLTE was disabled as I switched to 2G only and went back to 4G. After restarting the phone VoLTE was back there again.
