Any ideas how to remove a user who has checked out a Pro license from an organization??

We want to rename the organization's URL and we can't do this as long as this single person has his Pro license checked out....

Brent... assuming it isn't you apparently you can't see the Manage Licenses docs if it is checked out.

Keep in mind that Revoke All removes all checked licenses assigned to members. Also note that you cannot revoke ArcGIS Pro or Drone2Map for ArcGIS licenses from users who checked out a license.

This really doesn't make much sense, but at least you should have a full list of people that have been assigned licenses... you can then invite them all into a room...

UPDATE

Then this document Named User Licenses suggests there are ways to act as the terminator.

So you may have to check how your licenses are assigned and whether there are alternate ways for the Concurrent and Single Use licenses..
