I just ended up deleting the old one and syncing all over again since it didn’t take much time for the files to sync. But I have a folder that’s let’s say several GBs or bigger, what should be done? I did attempt just syncing them again but then I saw old files appear and decided fuck it.
Start by looking in the gui to see why it doesn’t sync, if there are sync errors (failed items) on the receiving side tap that to see details. Post screenshots if it doesn’t seem to make sense.
