The sign up was successful and after then sign up when I try to sign in I constantly first see some loaders that dashboard is being loaded and after then redirected back to the sign in page.
From the network I see 401 status error for get-me endpoint and 500 status for me
I’d suggest signing up with a different e-mail address. It looks like this domain is being automatically flagged and preventing sign-ups. Sorry for the hassle!
