Illustrator v23.1.1 & 24.0.3 creating .tmp files on server. macOS 10.14.6

Mac OS 10.14.6

Adobe 2019 (23.1.1)  and Adobe 2020 (24.0.3)  Both versions are up to date. No saving in background.

Test: User1  Create .ai file and saves to server. User 1 Close file.

User 2, opens edits saves to server. User 2 Closes file.

User 1 opens file again, but does not see changes user 2 has made.

This is creating multiple .tmp files on the server and files are not getting updates.

I also have a ticket in with the file server manufacturer, Nasuni. They are saying it is a Adobe issue.  But still don't understand why Illustrator is making these .tmp files.  Just started happing in the last couple months.

ANy ideas on how to stop illustrator from making these temp files?

Thanks,

Jeff
