In recent times handoff/continuity stopped working for messages on my iMac & iPhone. Messages coming into my iPhone no longer appear on my iMac, & I can no longer send messages via my iMac.
It has stopped working since updating to iOS 11 & High Sierra, however it still worked while I was using the developer betas of both.
I've checked the following...
- Both are on the same wi-fi network.
- Both have Bluetooth turned on.
- Both are logged into the same (my only) iCloud account.
- Both have handoff turned on.
Messages is the single biggest area where I use handoff & I'd really like it to be working again.
