WiFi Calling with new Fi app
I just noticed last night that my WiFi Calling on my S21 Ultra must have stopped working after the One UI 4.0 update (android 12 beta) or with the new Fi app that came yesterday. I worked on my router for a bit to ensure all was well and looked at forums which indicated to try disabling VoLTE on sim 1 (didn't work) plus looked for disabling WiFi calling within the Settings app. I could not of course find it and finally did think to look in the Fi app and there it was. My specific problem was audio out to caller from my Galaxy was not working although audio in to the Galaxy was.
So for the time being it appears on this device with Samsung's radio that Goog Fi WiFi calling is not working for me.

I had exactly the same problem on my S21U after the 1UI4 upgrade. I turned off wifi calling and have had no problems since.
