Hi, I am seeing the same issue. Any idea why this happens? I am syncing with 3 locations. Sometimes files appear in 2 out of 3. All seem to make it eventually but not immediately, sometimes it takes hours.
I have tried reducing the rescan_folder_interval from 600 to 120 seconds. How can I find out how long it takes to rescan so that i can adjust accordingly. My folder has 200,000 files in 20,000 folders and currently 1 terabyte.
