This is a reboot of Files wont sync unless I open the folder (2020, Windows) for Dec 2024 (and on Linux).
I recently moved a subfolder B directly from the Drive interface to another folder A. B was not synced on my PC, A was synced on my PC. B appeared properly on my PC but it was empty. Looking at the Insync window, it showed that B was completely synced (green icon). But double clicking on B in Insync window, it revealed many non-synced items (blue transfer icon). Short after it would sync all the sub-folders under B. But then again, opening the subfolders on local PC would show they are empty, until I open them in the Insync window, etc. to finally sync the files inside those subfolders.
I will sent my logs and out to support after posting this.
