This is possible using Trakt. Add a movie or series to your watchlist, sonarr & Radarr sync from this list and add to jellyfin.

There’s also a plugin in jellyfin itself for Trakt that can report back to say when you’ve watched it I believe.

Chromecast 4k is my choice

Think the “Quality Definitions” section of the settings in Radarr is what you’re looking for.

Additional complications here. My car is tuned for 99RON (UK). Doesn’t the US use MON or PON?

I had visual voicemail on my previous 2 pixels (O2 in the UK), but not on my galaxy s23 ultra on the same network. Seems to be a pixel/iphone exclusive feature.

Doesn’t everyone just use runelite anyway?
