One of the most frustrating things about Amazon's Fire TV devices are the fact that it's extremely difficult to find the apps you want in the device. I've taken to just going to the Amazon Website and searching for the apps, then adding them from the Website.
Oh, sure, there are apps available, but honestly, I do not find it a pleasurable experience. Quite the opposite.
Perhaps I'm just experiencing holdover from my general dislike for the Fire TV interface, along with the difficulty browsing Fire TV content on the device or on the Website.
I always hated that each season of a show was listed as a separate entry. I'd be scrolling through the content, and there would be Star Trek Season One (for example). Then more stuff, then Star Trek Season Three. More stuff, more stuff, Star Trek Season Two.
Don't get me wrong, I like the original Star Trek. I have since September 1966. But each season as a separate entry only junked up the browsing of content. Because it wasn't just Star Trek. It was every show. If a show ran 10 seasons, there were 10 entries. If another show ran 7 seasons, there were 7 entries. From these three shows alone, what should be three entries would be 20 entries. Like I said, just junking it up.
My takeaway from that was that the Amazon interface was full of stuff it didn't need to have. It was overcrowded, making things harder to find. And maybe I still carry a grudge.
I find searching for apps on Fire TV to be a bother. I hate the interface. Maybe I shouldn't, but I do. And I'll take the blame for being unreasonable. But I want Amazon to take the blame for being cluttered and crowded. That's why I will occasionally use a Fire TV device, but it's not a regular part of my Streaming Life.
