Additional Usergroup + Calendar permission problem

[Diego Vargas]

I have the following problem:

A private callendar called "MyGroupCalendar" is created and the calendar permissions are set so that only members of the "MyGroup" usergroup can view/post/access it.

Registered users cannot view the private calendar.

Registered users apply to a "Public (Joinable) Custom Usergroup" called "My Group" via Settings->Permission groups.

The Usergroup leader for "My Group" adds the registered user to the group, however they still can't view the private calendar.

Any idea of why this is happening ?
