I've noticed that I cannot play radio stations that I have added to Navidrome. The player just shows a cycling icon and the radio won't start playing. Looking at network activity, I could see the browser complaining about CORS issues: it cannot deliver content from a third-party domain. It turns out the issue is known and there should be a fix available in the next release: https://github.com/navidrome/navidrome/issues/2267 .
