Periodically through the evening, the view went black and the Oculus showed the blue guardian grid (a couple of times I saw my Oculus home) - although the game audio didn’t cut out. This lasted about 3 seconds each time and happened about 10 times in a 4 hour period. It happened in the overworld, in town and in dungeons
I spoke to some other players who were having the same issue. One said it has been happening to them for a few days,
I’m on Oculus Quest 2.
