There is an audio problem since upgrade to macOS Big Sur 11.0.1. The incoming audio is extremely distorted at the beginning of the call. 2-3 end calls and log-ins seems to clear the problem after 1-2 minutes.
I have not found another workaround as of yet, and it was very disruptive to my sessions today. Hopefully there will be a quick fix?
My bad for being first on my block with upgrading operating systems.
