For a few weeks now, I've been seeing a halo on the top of the left lens. The lens is perfectly clean and unscratched, so I think it's internal condensation. It looks like an oily fingerprint on the internal part of the lens.
Two days ago, I made an appointment with an Apple Genius, and I went today.
They aren't allowed to perform a physically test on the device; the only thing they could do was run diagnostic software to send it in for service.
I'm on the VisionOS 26 dev beta: the diagnostic tool doesn't work with the beta.
Furthermore, my ticket was flagged as 'resolved' even though it isn't, so I have no way to receive an additional solution.
Result? After an hour, I still haven't solved anything, after spending £3,500 on the device and £500 on Apple Care Plus.
What should I do?
