Does not anwser controls from other device ("Cast")

[Tina-otoge]

Jellyfin has a feature called "Cast" that allows you to control a device remotely. If I'm listening to music on Gelli on my phone, and that I use my computer to access the web UI, I can see what is playing on Gelli using the "Cast" button in the top right, however if I try to pause, seek or change song, nothing happens.

Not sure if it is a bug or feature request as I don't know if Gelli supported this in the past.

Here is a screenshot of accessing Gelli using Cast

However when trying to use the controls while remotely controlling Gelli, nothing happens.
