Some group categories were setup from a Groups > (Group name) >Content Tab.
The group categories work as expected from the Groups > (Group name) > 'Content Tab' View.
However, if the group categories are accessed from the Content > My Groups > 'Group Name' > 'Select a group category'
The group categories don't work. Some interesting observations and information are:-
1) The quantity next to the group categories are accurate (January (23), February (14), etc )
2) If no group categories are selected, all items are listed.
3) The account I'm logged in with is an administrator account.
4) The content in the group is created by another account in the organization.
5) ArcGIS Enterprise is at version 10.6.1.
Why don't the group categories filter content when viewed from the group category options available under the content tab of the Enterprise portal?
