Cannot enable 'unlock your Mac with apple watch' feature
This feature was working fine up until a couple of weeks ago, but now the option is switched off in settings and refuses to switch back on. I've followed all the instructions on the site, my watch and Mac and iPhone are all logged into the same iCloud account, they are all on the same network. I've unpaired and re-paired the watch, restarted my Mac and restarted my phone. I've checked that they all have the latest updates. But I still cannot enable the feature, it just flips straight back to off.
