I can't sign in / the sign-in button shows an error.
Most sign-in problems clear with one of these:
1If you created your account with email and password, sign in that way instead. Accounts created with Google sign in with Google (or set a password via “Forgot password”).
2If you see “sign-in isn't available yet”, that provider isn't switched on for your environment. Use another sign-in method and tell us — that one is on us, not you.
3Stuck on an error page or a loop? Retry once in case the provider was briefly unavailable, then email hello@montyai.co from the address you're trying to sign in with, include a screenshot, and we'll unblock you — usually same day.
