Server Version#: 1.43.0.10231
Player Version#: PM4K (Plex for Kodi) - not sure it matters.
I don’t usually enable the plex pass, but I saw the transcoding version and I thought to see if there’s something that breaks.
It wasn’t transcoding that broke, but rather the ability to skip credits.
As soon as I rolled back to the stable version it started working again.
This should be fixed now in the latest beta.
