Meta Quest dashboard login not working

I'm not able to login to dashboard with my other account. Cannot also access this forum with that account. Everything works fine with this one, but if I use the other one, I get error message. The actual login seems to work but after it goes through I get "Oops, you seem to be lost" error. I tried to invite that account to my organization, but when I click the link from email I again end up to error page after login. If I try to login with this account, I get in but get error that the invitation isn't for this account (obviously). But in summary: login, links and dashboard works fine with this account but not the other. Sadly that is the admin account for my Quest 2, so I'd really need to get the dashboard working to enable developer mode.
