I have the newest beta test release (Quest) and something changed from my last version. It no longer displays the posters I set. It splits them into categories so that it shows:
VIDEOS (where it auto-generates the thumbnail for the movie) IMAGES (to view the jpg only)
Bijon Hello, thank you for your feedback.
How did you play the video, from local storage, or via SMB, DLNA or AirScreen?
You can restart SKYBOX app and check if it resolves the issue.
