When adding a new user using the https://cloud.sensopia.com/newuser.php API endpoint, it succeeds with status: 0 - "Your account is now configured to send floor plans directly to Workspace Name".
But when checking the list of users either via https://cloud.magicplan.app/workspaces/members/active or via the https://cloud.magicplan.app/api/v2/workgroups/users API endpoint, this new user is not present.
Additionally, if you use /newuser.php enough times, it will eventually respond with status: 48 - "We could not find an empty seat to assign it to this account. Please add a seat to your billing first". But still these users do not appear in the user list - this even works if you add the same user repeatedly, each is seemingly counted as a separate user.
