In the Org Admin portal, I can tell if a user hasn't logged into Bluebeam for X days by looking at the Last Login column. However, if the user has been assigned a license, but has never logged in, there's no way to tell how long ago the user received the license. Did they just get the license yesterday? Have they had it for 6 months? There's no way to tell.
In the old Org Admin portal, if the user had a license but had never logged in, then the Last Login column show "Created on [date]". This at least indicated when the user had been given the license.
It would be really helpful if the current Org Admin portal had the same and/or similar functionality so that you could tell when a user was assigned a license.
