We are noticing an issue where the file conflict check (if the file has been modified on the server since you started making changes) is not working in certain cases. It seems to work for users in the same time zone, but we have a developer in a different time zone who is seemingly being allowed to overwrite changes and not receiving an error message about pulling the latest.
Could this time zone difference be the issue? Not really sure what is going on here, but that is our first thought.
How is the file conflict check done?
