Intermittent problems

I'm getting a bunch of intermittent problems 24 hours in on brand new Ray Ban gen 2 with iPhone 13 running iOS 26.0......

Can be on a call for 45 mins via glasses to iPhone and it's perfect - love it. But end call, start a new one and the glasses disconnect, reconnect, disconnect, reconnect, disconnect (and repeat) all the time - typically between five and twenty seconds connected then not-connected cycle. 

The white notification LED will be on and stay on until I put glasses back in the case. Then they'll be fine. Then later on the same issue again. 

Touch Bar has a mind of its own. It'll be fine, then you can swipe volume up but not down, or it won't respond to one tap to pause, but will respond to two taps to skip a track.  Sometimes you can start AI with a tap, other times not. Then "OK, meta" will work, but "Hey meta" won't. Then "Hey meta" and "OK meta" will work but tapping the Touch Bar won't.

80% of the time Meta AI app recognises the glasses, then it won't (glasses are switched on but "Not Connected"). Later on it will. 

Camera button: sometimes pressing will take a picture, other times not - you still hear the 'shutter' click but nothing captured.

Video - quality better than I'd expect but image and sound are sometimes out of sync. Left speaker creates a strange crackle when recording sometimes (you hear it during recording but not on play back). Video import hangs (24 second video importing for over ten minutes before I gave up). 

Factory reset (twice), software update, unpair & re-pair (many times), delete Meta AI app/reinstall.... Short of hitting with a hammer I've tried the normal set of problem solving actions. No issues with case or glasses being charged. 

Are these issues highly unusual, or is it part of the 'undocumented feature' set one has to live with? 

.......Never had a piece of tech that needs so much nursing.
