Not showing all thumbnail

Is this normal? Some show and some don’t in my TV folder. All show up in movie folder

Infuse has some special logic to show thumbnails at the series level if the items inside are organized into folders by Season.

E.G.

Shooter (2016)/Season 1/[files]
Shooter (2016)/Season 2/[files]

This will become greatly improved and much more flexible once our Library option makes it to iOS. This is currently planned for an upcoming version.
