Continuity has been working great on my 2015 rMBP, up until a couple days ago. Continuity would work between my Watch and iPhone, but not to the MBP. It eventually worked itself out. Then it happened again this morning. Call Handoff was working but not the other Continuity features, so I figured something was up with Bluetooth. I tried to turn it off in Settings, but no matter how many times I clicked Turn Off, it wouldn't. And it beach-balled on me several times. I was able to reboot and upon relaunching, Bluetooth was off then I turned it back on and Continuity was working again. Anyone else experience this? One time glitch? Software bug? Hardware issue?
