Smart Flow not working

App version

Beta

Issue description

Issue description:
Smart Flow’s sonic-analysis-based modes (Transition Maestro / Echo Match / Steady Vibes) stopped working. The options are selectable but produce no effect — the current track plays normally, but no tracks are added to the queue.

Device type: Phone (Samsung S23, Android)

Media provider: Navidrome (self-hosted), with the AudioMuse-AI-NV-plugin for sonic analysis (AudioMuse-AI backend)

Versions: Navidrome and the AudioMuse-AI-NV-plugin are both on current/latest versions.

Troubleshooting already completed:

  • Confirmed AudioMuse-AI analysis job is fully complete
  • Confirmed via Navidrome web UI that Instant Mix works correctly (pulls sonically similar tracks)
  • Confirmed Radio Mix in Symfonium works correctly (queues tracks fine)
  • Confirmed no track ratings are used in my library (ruled out the low-rating exclusion behaviour)
  • Confirmed Navidrome and the AudioMuse-AI-NV-plugin are both running and healthy (checked admin/plugin status)
  • Ruled out network/connectivity as a cause — tested while actively streaming non-cached/non-downloaded tracks successfully, on the same connection
  • Forced a fresh connection re-test and removed/re-added the Navidrome server in Symfonium — no change
  • Forced a full library re-sync (not just a quick sync) in Symfonium — no change

This is my first time posting an issue – apologies if I am not doing it correctly.
