So if I where in your position I would see to migrating the SSO users to normal users.
If I remember correctly I did test that some time ago.
When SSO users exist and try to login and there is no SSO support it shows a migration message for that user.

We don't get the option to add a user manually it seems. When I try to "add user" in the top right profile menu, I get a redirect as the same user. I can't seem to create new users that way.
When I try to invite to a document using the link, I get the Cloudron login page (if I'm using incognito, otherwise it just logs me in as me automatically).

Honestly, a completely enshittified experience. Anyone reading this.. don't bother with this app if you're starting out, it's only going to get worse.
