I had a new employee start. We have a group called "employees" and I added this user to the employees group. When the user logged in, they cannot access the "Employee Resources" space even though the user is in the employees group, and the employees group does have access.
Adding this employee as an individual in the Space Permissions page allows them to see the page. However, we also have certain pages that have restricted access, and explicitly grant access to employees.
Other users are set up in the identical way, and work just fine. This seems to be some type of glitch in setting user permissions based on group membership.
