This is very troublesome... It is possible to create a general, personal Google account using any email address (iirc) so I wonder if it is possible to just migrate to your own email solution (since you own the domain) and keep the google account, or at least migrate it to a regular account.
It appears this is not possible. I don’t need any of the G Suite features, and I don’t even need email. I just need my single user inside G Suite to be converted to a normal unmanaged Google account but there doesn’t seem to be a way to do that.
Some people are saying if you convert your account to Google workspace then cancel that then you end up with what you want. You'd keep Photos and YouTube but no Gmail, contacts, calendar etc. I'm trying to discover if this is true.
