Allow Handoff between this Mac and your iCloud devices under System Preferences > General keeps turning off for me. I notice this at least a couple of times per day and it’s been happening for a good while now, both with my previous 16" MBP and my new M1 MacBook Air.
Anyone experienced this and found a solution?
I’ve had this same problem but haven’t checked to see if it is shutting off. I just notice that my copy/paste from iPhone to Mac isn’t working. I’m on a MBA M1.
