I have an Excel file (.xlsx) in DT 4 on my mac. When I edit the file in Excel using Open with and save it the contents of the file update but the Modified field in DT does not seem to update. This means that the file does not sync. When I check the file in the finder I can see that there is an update in the “Date Modified“ field.
