Account Mishaps = At Wits End

Hey,

I'm in a crazy 2FA loop with my meta account (original email, still have access, did account recovery, have facebook account access). Trying to recover my library on Quest 2, but I can't seem to get into the Meta account whatever I do. Keeps redirecting me to this one.

Any help would be super appreciated, and I don't know where to go. The Support system refuses to take my Quest 2 serial number, and they can't find my email either.

Any ideas?

Thanks!
