Facetime issues
When I receive a video call (or video call someone), the screen appears black, they can't hear me and I can't hear them either. The same thing happens with audio calls - I can't hear them and they can't hear me. The only solution I have is to call the person again (or them calling me again) in order for the FaceTime call to function properly (although it doesn't always work - it works most of the time).
This is in spite of my Mac being updated to the latest OS (macOS Big Sur 11.4).
I would appreciate someone's help since this wastes a GREAT DEAL of my time and productivity.
Thanks
MacBook Air 13″, macOS 11.4
