Chromecast in JF never worked…
When I click the chromecast icon in JF “Play On” (top right) I get “Google Cast Unsupported”.
How did you manage to get it working?
JF has no proper chromecast support… ☹️😤
Windows browsers such Firefox, Chrome, Vivaldi, Brave have the same issue. It’s not OS or device related, it’s how Chromecast has been implemented in Jellyfin.
