So something very strange happened in last few weeks. I am on wifi at home and had absolutely no problems making or receiving calls while on wifi. The last update, I did activate wifi calling to use wifi as preference but still seemed to work fine. However now, when making or receiving calls on wifi, there is no audio at all either on my end or their end. Now if I turn wifi off, everything is normal but it is when wifi enabled, there is no audio. I even went in and changed wifi calling option. Anyone else having this problem?
