I feel like the problems with their app are more algorithmic than in the implementation details. I once had to go edit my watchlist on amazon.com because I had added enough movies that whatever super-linear algorithm they were using simply could not comprehend my watchlist and the input watchdog timer would murder the app. And come to think of it that was when I used Prime on a Roku, so it's a cross-platform problem (yay, WASM!).
