FaceTime not ringing on Mac after Big Sur update
Since updating to Big Sur last week, incoming FaceTime calls no longer ring my 2019 Retina 5K 27-inch iMac. My iPhone, iPad (iOS and iPadOS 14.2), and MacBook Pro (High Sierra) all ring and I can answer the call on any of them, but on my iMac I see no indication about an incoming call. If FaceTime is open on my iMac when the call comes in, I immediately see the incoming call listed as a Missed Call while my other devices continue to ring, but I can't answer on my iMac. I can still make outgoing FaceTime calls on my iMac as usual.
So far, I've restarted my iMac, and I've signed out of FaceTime and signed back in. Does anyone have any suggestions? Thanks.
