### Bug description

Environment

- Nextcloud Desktop 3.30.7
- macOS Tahoe 26.5.1
- Nextcloud Hub 10 / Server 32 (Hetzner Storage Share)
- Virtual Files (File Provider) enabled
- notify_push enabled

Problem

The desktop client reports "Everything synced", but files uploaded via the web interface are not downloaded to the Mac.

Observed behaviour

- Uploads from macOS to the server work correctly.
- Downloads from server to macOS do not.
- The tray icon sometimes changes to the warning triangle.
- The activity view occasionally stops updating correctly.
- notify_push is installed and enabled.
- A debug archive is attached.

I have already verified that notify_push is enabled on the server and that brute-force protection is not the cause.

The exact version in which the issue first appeared is unknown. It was noticed while using the current 33.0.7 client.

### Steps to reproduce

1. Upload a new file via the Nextcloud web interface into a folder configured as "Always keep downloaded" (Documents).
2. Wait several minutes.
3. The file never appears locally.
4. The desktop client still reports "Everything synced".

### Expected behavior

Files uploaded via the web interface should be downloaded automatically and the sync status should reflect the actual state.

### Additional info

_No response_

Start by reviewing the attached debug archive and the Virtual Files/File Provider synchronization path in the macOS desktop client. Reproduce the issue by uploading a file through the web interface into an “Always keep downloaded” folder, then inspect why the local file and sync status are not updated. Done means server-side uploads download automatically and the client reports the correct status.
