As the subject says - recently I have noticed that updates made to a file on another machine are not synced to my mac. If, however, in the folder where the file in question lives, I create a new file, then it wakes up and synchronizes everything properly. This has turned odrive from being the reliable tool around which I organise all my data into something that is now almost completely useless.
Details: odrive prod 6344 on High Sierra; synchronizing OneDrive for Business.
