Apple TV Personal Library Movie/TV display tiles not appearing

Major issue with new release and personal movie library. I have a LOT of movies I've acquired over the years (800+), and the TV App > Library > Movies list refuses to display the tiles for more than 75 of them, leaving me with empty tiles.

Switch to another category (Drama), and I'll see the first 75 of them there. Some for Comedy and so on.

Exactly 75 of them, to be exact. The first 75. Each and every time.

The only time I see all movie tiles for a category is when there's less than 75 of them.

Worse is that tvOS 26 now doesn't even show the title for selected tiles, which means I have no clue what any of the tiles w/o posters actually are.

The previous version (tvOS 18) had this problem intermittently, with tiles slow to appear. Now it seems to be permanent. (And 75 each and every time? A bug somewhere.)

Rebooting and restarting doesn't help. Even reset Apple TV and reinstalled OS. No joy.

No issues elsewhere, just downloading movie tiles in my personal library seems to be affected.
