I have Subsonic 5.0 beta2 installed and have a Chromecast and the Subsonic Android app. Maybe I'm being dense, but I can't seem to figure out how to cast from either the web interface or the Subsonic app. I'm familiar with casting Netflix, YouTube, etc. I feel like I'm missing something very basic that's maybe keeping the Cast icon from appearing. Any help would be appreciated.
I have a .subsonic.org address for my server but I see no references for casting except the vague "Subsonic now has Chromecast support" posts here in the forums. A screenshot of what I'm supposed to be seeing would be great!
