Unlock with Apple Watch S2 fails with no reasone
Hi!
For some reasones my Apple Watch S2 sometimes won't unlock Macbook Pro (15" Mid15). The text "Unlocking with Apple Watch..." hangs for 5-10 seconds and then password field appears. Both my iPhone7plus and the watch are right next to the macbook. No errors shown.
Restarting Macbook helps, but not for long.
Any ideas whats happening and how to fix this?
MacBook Pro with Retina display, macOS Sierra (10.12), Iphone 7 Plus & Apple Watch S2
