In Portal 10.9.1 we could add a user to multiple groups at once through the Members Detail page. Now in 11.3.1 (for an existing user that has created their account automatically on login) I can only add a user to groups by opening each group and "Invite Member to Group" and searching for the users account and adding them to the list.
With the previous workflow in 10.9.1 I could find the user in the members page and add them to all the groups they needed by simply clicking a box next to all the groups and get them added all at once. This new workflow is much more inefficient especially if adding them to a handful of groups or more.
I'm aware there is a workaround workflow if I'm creating the user account for them as an admin, but our Portal is configured to create their account on their first login.
