Airdrop, Handoff, Continuity, Universal Clipboard, ... all great features but sooooo unreliable. Does anyone use these features all day without problems? I move a lot (home, office, ...) switching between wireless networks and it seems these features cannot keep up. They work 25% of the time, and it's never clear why they do or don't. Usually rebooting one or more devices fixes the problem, but that's such a windows solution. Because they are so unreliable I seem to forget about them after a while. Anybody better results or solutions?
