Server Version#: 1.18.5.2260
Player Version#: 4.17.1 (tizen 2.4.0)
the app on samsung (tizen) does not show EPG and in currently shown there are only 8 shows displayed and you can’t show more. if you move to the last show and back it crashes.
I can’t replicate this on my Samsung with tizen 3.x installed.
You can try deleting the Plex app, turning off the tv, removing power for a few (unplug from the wall), power up, and reinstall the Plex app and see if that helps at all.
