Have you tried using the physical buttons? Just to see?

Click on it and it (the ITunes Extras tile)will show you a preview menu… it may not be 100% complete, depending on how they formatted the menus, but it shows a fair amount of what’s in there.

Just can’t advance past the menu.

Not noticeable unless you have a proper home theater full of high end equipment.

Carry that shame with you forever!
