Conditions have a new option called "Condition Logic". Your two choices are:
Option 1 applies to checked items only. Option 2 applies to all items that are NOT checked.
This new logic has been added to reduce the annoyance of checking numerous options for the condition.
Registrations that belong to a user require you to impersonate the user to access. If your backend permissions do not allow you to impersonate users, you will not be able to view the registration on the frontend.
