I just ripped a few episodes of a TV show, added them to iTunes, updated the metadata, then synchronized them to my iPhone 6 running iOS 10. However, the episode doesn't show in the TV app. Other episodes that I ripped and synchronized do show up.
When I look in Settings > General > Storage & iCloud Usage > Manage Storage > TV, it shows the missing episodes, so they are on the device.
Why doesn't the TV app show some of my TV show episodes?
