Unable to self-host with "Single Community"

I was able to get single community mode enabled, but new users do not auto-join

@zixhaa I did not experience this issue, users were able to auto-join when creating an account for me. I did not share a "guild invite" but instead just gave them the URL and it presented them with a "create an account" screen and they got in without additional steps. Try the URL without the /INVITE= and see if it lets them in.
