Issue description

Since a recent update, Symfonium can no longer sync with a Navidrome server via the Subsonic provider.

Phone

Media provider

Subsonic (Open)

Steps to reproduce

  1. Open Settings.
  2. Go to ‘Sync Manager’
  3. Tap the ‘Sync’ button next to a Subsonic provider.
  4. The UI briefly flashes but the sync never starts. New media on the Navidrome server is not picked up.

Additional information

This Navidrome server has been syncing successfully until recently and no changes have been made to it. Deleting the Subsonic provider and recreating it does not fix the issue.
