Issue playing 4k with Plex Preview app for Roku. These videos seem to want to transcode to 1080p. Works fine in regular.
We should have a fix coming out later today to fix the preview regression.
The preview update is available.
Thanks. Tested good. On one of my rokus I still had to reset the whole roku to get it to work (prob some cache or file left behind for the plex app). Another roku worked right away.
