Air drop has suddenly stopped working on el capitan.
This is the Mac I have. Suddenly since the last few months, after IOS 11(i think) my mac doesn't recognise any devices. It was working fine earlier. My iphones settings fine as it works between me and my husbands phone(both iphn8). I have done all trouble shooting on OS too, nothing. Can someone please advise. Thanks
MacBook Air, OS X El Capitan (10.11.6)
