Just received the new UI on our upstairs Fire TV Cube. I really dislike it. Now, in order to find the app I want, I have to scroll down to "recently used" rather than having my favorite apps on the start page. I also can't choose the input without going into the menu.

Why did Amazon do this? How would they like it if we changed the keyboard on their computer or controls in their car overnight? And no user guide for the new UI, just dive right in and expect it to be intuitive. Well, they have taken away a lot of options (like arranging apps in the order I wanted them), so I guess it's "simpler," and OK if you happen to like whatever the Amazon devs like.

The best part? Our upstairs Cube has the new UI, while our downstairs Cube still has the old UI. Well, at least for a while, I'll enjoy our downstairs Cube and gnash my teeth at the upstairs Cube.

I've done every factory reset and setting change I can find. On the home screen, I can click through any row up/down/sideways without problem except if I linger for a couple seconds when I get to a sponsored content row. Then the screen goes black and reloads the last screen (no matter whether that's the top of the home screen, an app, or even a settings menu screen).

I can quickly click past the sponsored content row, but wondering if I should just deal with this quirk or seek warranty coverage.
