This is not a star issue this is more about having the proper information 
Always contact support and devs before bad rating with assumptions that can be wrong.
Airsonic was contacted Search3 API behavior 路 Issue #885 路 airsonic-advanced/airsonic-advanced 路 GitHub they no more update their app. So just enable the compatibility mode when configuring the host as the wizard tells you to. (And the wiki see below)
[Wiki] Subsonic / OpenSubsonic - media provider configuration .
- Airsonic: GitHub - airsonic-advanced/airsonic-advanced (Require compatibility mode - No more maintained, not recommended)
I would highly suggest that you migrate your server to something more secure and maintained like Navidrome. (https://www.navidrome.org/)
