I and my wife use TD3 and TDPS. She is using 3.0.5 (169) and I have upgraded to 3.0.6 (188).
When I change a file and it is sync'd via my server, both she and I get the activity message saying it has been changed and sync'd.
However, when she changes a file, even though my copy gets updated, there is no message in the activity log. If she creates a new file in a space or deletes a file in a space, this is noted in my Activity log - just not changes to existing files.
Sometimes, for a short period, I get "RegServer not reachable" but this clears within a minute or two but doesn't fix the above issue.
May I make a suggestion - can an extra column be added to the Activity Message panel called 'Action'. When referring to a file or directory, it could have one of the following values: Created, Modified, Deleted.
