I have multiple different folders that are syncing across 4-5 different devices and there is only one that is giving me fits. It syncs fine on 2 devices but my third device (running Unraid) will properly sync it and then 1-2 days later the marker disappears and it shows an error message.
It appears that the data is still there but where does the marker go?? I then need to remove the folder, re-add it from another device and then allow my Unraid server to rescan (which takes 24-48 hours.) How can I find out what’s going wrong?
Are you using more than one instance and work with the same folder? If this the case and you add and delete a folder in one of the instances, the folder marker is also lost for the second or other instances.
