Cannot play 4k content on Chromecast Ultra after latest Plex Server update
I'm having a problem with playing 4k video on my Chromecast Ultra after latest update to version 18.104.22.16803.
Now every time I try playng video on Chromecast it just stops playing and displays "Ready to Cast" screen.
I'm playing the same video file I've played on it before: 4k, HEVEC, 67825 kbps. Detailed info is on screenshot below:
What am I doing wrong? What happened?
