WatchOS 27 Update Issue

I have downloaded the WatchOS 27 update.


There is no option to apply the update, and it did not install overnight.


I have restarted the watch and the iPhone with no success.

Try this in your watch (not on the phone): go to Settings -> General -> Software Updates -> Install. It might require that you confirm the update on the phone and place the watch on the charger.


There seems to be a glitch in iOS27 that prevents the installation from being started on the phone.


I hope this helps.
