that only helps if the user is still in the reference file. If that person saved and closed, then you get the 'unkown' result. My issue is not identifying the current user, that is actually known. The problem is that AUTOCAD is identifying the previous user of that reference file in the notification, not the actual last person who saved the file.
Let me reset the situation. You reference a file (DWG B) last saved by USER B into your file (DWG A). You notice a change needs to be made, so you open DWG B and make the edit yourself, save and close. Back in DWG A, the xref notification opens and says USER B modified the file and needs to be reloaded. Clearly, USER A made the change and not USER B.
Second step, USER A then notices another edit to DWG B that is needed. DWG B is opened again by USER A and edits made, saved and closed. Switching back to DWG A displays the xref notification that USER A made a change to DWG B and needs to be reloaded.
The above happens without any customizations to AutoCAD and happens in 2022 and 2023 to different users in different companies.
