Please allow multiple devices (Chromecast, individual plex players, anything) to be grouped and then cast to synced simultaneously.
The way this can work is in the cast section, instead of picking one device to cast to or one Chromecast to cast to, we can multi-select Chromecast devices and plex players, and then either play it or save it as a group to cast to with 1 tap later.
This feature should be available across all plex player apps, and it should work similarly to this app: https://www.microsoft.com/store/productId/9PKWLJG2W3GK
Multiroom Audio Cast is something that’s becoming a thing in Spotify, Apple Music, and has always been there in Sonos; it would be amazing on Plex due to the sheer flexibility it provides.
