 ## Known Issues / Notes
 - Not all server implementations accept an empty string as a search query, however this is considered valid input per the API documentation. If search or track enumeration fails, ask the authors of your server implementation about handling empty query strings.
 - This provider makes use of https://github.com/khers/py-opensonic for communicating with the server, if something is failing to work properly in Music Assistant, try to use that library to interact with your server (can you ping it?, fetch artist and albums?, can you search?).
+- If you find a mismatch between what is displayed by your Subsonic compatible server and Music Assistant then refer to and contribute [here to help find a solution](https://github.com/music-assistant/hass-music-assistant/issues/2192)
