I set up an account last week to ask a question on the forum but didn't think that I created a Metabase instance. But now when I try to open a Starter account it sends me to Login.
I never received an email that DomainName.metabaseapp.com was set up for me.
The "Find your account" screen says:
If you remember the URL of your Metabase Cloud, enter it here:
If not, check in your invitation email for a login link, or ask your local Metabase Admin for help.
I have no way of knowing my domain name.
