### Bug description

I have a folder where I dump my scans from a mobile phone app. That folder now has 1,500+ files. The server has no issues managing these files, and the web and iOS clients display the correct file counts and latest files. However, in Finder on macOS, when using FileProvider/VFS, the folder has stopped updating with new files, and it's missing 100+ of the latest files. On the iOS Files app, the folder times ~30 seconds to load, but all the files, including the latest, are present.

I also tested this by uninstalling Nextcloud macOS client completely and doing a fresh sync. It syncs correctly the first time, but eventually stops. (Not sure exactly when; right now, it's been out of sync for 2 months again.)

### Steps to reproduce

1. Have a folder in Nextcloud with 1,500+ files
2. Add a new file to that folder from somewhere other than the macOS FileProvider/VFS client
3. Check the folder in Finder on the machine using the macOS FileProvider/VFS client
4. Note that the folder **does not update** with the most recent added file
5. Note that the Nextcloud client int he menubar thinks everything is up-to-date
6. Force a VFS sync in the Nextcloud menubar client
7. Again, note that the folder **does not update** with the most recent added file

### Expected behavior

Same as above, but the folder does update appropriately.
