It's still happening with me. For the last week or so I was intermittently forced to log in again to SLR on DeoVR, which never used to happen. The problem got worse yesterday when there was an "unknown problem" which rejected my login, but a few hours later the login worked okay.
Today I had no problem the first few times I visited the site, but now I find myself logged out and get the "unknown problem" again when I try to login. Hopefully it will correct again, but the login problem is still going on.
However, my headset is a now-unsupported Oculus Go, so I guess this problem doesn't matter unless some Quest2 are experiencing it.
