The Jellyfin app on my Android phone runs normally when not connected to Android Auto.

But when AA takes over, and I run Jellyfin on AA’s dashboard app list, it shows the screen below:

Doesn’t seem like it is accepting any input. Is this an issue or have I missed a step?

Edit: problem solved. Or I should say there is no problem in the first place. Jellyfin AA simply only plays audio, and it doesn’t support video playback period. My Jellyfin only has videos hence “no item” (no audio item).
