All of this has been tested thoroughly and all of this points to MS TEAMS not allowing use of external microphone. Every device tested was brand new when tested. You software has a patch issue with the mic source with in the app itself. You cannot choose the same settings as you can from the desktop version, and in addition you cannot access MS TEAMS on any browser because you don't support that either. Congrats on effing up the standard.
I have ZERO Faith that MS is going to resolve this issue. but thanks.
