The last 6 months or so something changed in Plex where Dolby vision files in MKV would play for most profiles.
Just recently within the last week or so they no longer play. A “file not supported” error happens stating that the codex does not work in MKV.
I hope SO MUCH that we can fix it because I have been so happy that Plex finally started supporting this.
Infuse also won’t play them anymore correctly so I think this is server related.
