Same issue here. Everything working perfectly fine with BigSur. Unfortunately I can't downgrade back since I don't have a back-up from that time (I know, was dumb) and since my MBA M1 won't detect usb, I can't create a bootable one.
Apparently this happened too with BigSur launch and took them 2-3 months to fix it so... Yeah.
I have a feeling Apple is just going to go with the "Sorry, your device is no longer supported so buy another one and pray it works" route.
Hope I'm wrong on both instances though.
Has anyone experienced this with a KVM switch? Just wondering.
