Showing up offline for friend, but not vice-versa

Recently I’m often shown as offline for a friend, while I see them as online. The day before it was the other way around. We’re in different regions, and I suspect it’s related to some kind of inter-region server sync?

There’s nothing on my side that I can do to fix this, is there?

I am now getting this Bug too, on Vrc site people are in worlds but not in game.
