Groups owned by other admin don't appear in "Manage group membership"

[ChristophK]

In my Portal 11.3 there are two admins. Admin1 and Admin2 have each created a bunch of groups.

Now Admin1 wants to add a user to a group owned by Admin2, but that group simply does not appear in the "Manage group membership" dialogue reached via Organization > Members > mark a member, More > Manage group membership. 

I have tried a bunch of things and came to the conclusion that the group setting "Who can contribute content?" is the culprit: When it is set to "Group owner and managers" the group is not listed. When it is set to "All group members", the group is listed as I expect it to.

When I add a new member to my org via Organization > Members > Add Members, the missing groups are listed. Admin1 and Admin2 can also see each other's groups in Groups > My organization's groups.

I think the GET request which happens in the "Manage group membership" window has this query part misplaced somehow:

(owner:Admin1 OR isviewonly:false)

Hey @ChristophK,

I was able to replicate the behavior that you are referring to. If you add a user to Group 2 and you go to Organization > Members > Select the Member you added to Group 2 and click Manage group membership to change its membership, you will see that there is already a group selected which is the Group 2 (created by Admin 2).

I have tested from the Groups tab and I was not able to see any difference between Admin 1 and Admin 2.

I think if this issue is disturbing and you need this functionality, you should get in touch with Esri Support

Thanks,

Glen
