Tried to log in, and I just got blocked for suspicious activity, asking for a verification code from an email that I'm not logged in at this moment. So unable to verify!

I doubt they send the email anyway. They just told me cannot currently register this email" through the automated error message so I couldn't even re-enroll a security key for the 4th time. Not that it would change anything.
Let me try again wait!
Will update in a couple of minute...
Update: After 3 attempt, I was able to login.
1st time, suspicious error.
2nd time, after giving them code, something went wrong.
3rd time, finally realised I was the real owner.
Tbh, I don't use it for the pain it gave me! Out of nowhere they would lock me out or suspend my account. That really sucked.
