Sync problems on Windows junctions


I wanted to have a folder synced in my Seafile library that is located on a different hard drive.
I created a Windows Junction to that folder inside my Seafile library folder.

Everything seems to go well initially, it works as intended. However, I have noticed that the files within this Junction are only synced when my Seafile client starts up. Once started, the modifications to files within this Junction are basically ignored. The Seafile client does not show any errors and says the library is up-to-date.

I use Seafile Server 9.0.10 under Ubuntu 22.04.1 with a MySQL 8.0.32 database and Windows client 7.0.9.

Any help appreciated!
