Since the update I have some issues with VoLTE calls (very bad voice quality) and LTE in general (very slow connection speed).
So I wanted to switch off VoLTE, as @asmaron suggested before (in another context):
Unfortunately this option is missing on my FP3+:
Anybody else is missing this option?
Edit: I am using Vodafone Germany.
(I know this is a user forum. I also contacted official support about that, but I would like to know if there are more users missing this feature.)
