I noticed this same issue today... I'm using DEOVR with Quest 3 (latest updates made)
Today I was logged out while using the DEOVR. That really ruined "the mood" when I had to start logging in again.
I understand, if user has 30 day membership and SLR wants to make sure that the membership is valid... but I have Lifetime membership.
It would be good if the site recognized the user's membership type and there would be no need to make such unnecessary logins.
