has anyone else experienced some Continuity features like Handoff not working in the GM? i'm on a 2011 iMac, but put a new Airport card in it to allow everything with Continuity to work. it was all working great until i updated my iPhone to the betas of iOS 11 not too long ago and then it just stopped working. i thought maybe going up to the GM of High Sierra would fix it, but not luck. oddly enough, it's not everything...Airdrop has still been working fine and i believe Universal Clipboard although i'm not positive on that one.
