Hah, I was going to say, I do check for updates at least once when I first get it, because I have run into TVs that shipped with HDR bugs in the stock firmware.

For the Chromecast, what happens with yours? Mine randomly restarts, or reconnects to wifi, or sometimes Plex has trouble buffering until I reboot it.

I recently bought a raspi5 to try out FCast, though currently afaik only Grayjay supports it.
