Fair point. Here's what I mean:
On iOS 10.0-10.1.1, when you tap the Now Playing section of the bottom bar (on the right) in the Music app, the panel slides up revealing the controls, volume slider, shuffle button, lyrics, etc. Notice how the width of the pane stays the same width as the view is when it is collapsed in the bottom navigation bar and the rest of the music app is visible on the left.
On iOS 10.2 here's what the Now Playing view looks like. It takes up the whole screen.
Now, you might be saying that Apple simply made a design change. But, I don't think so for a few reasons. First, all the elements on the 10.2 view are the same sizes as they were on 10.0-10.1. There's just a bunch of wasted white space now. Second, the arrow to minimize the view at the top is partially covered by the clock and is very difficult to tap to close. That hardly seems like a deliberate design choice. Finally, and most importantly, the animation when closing this view is glitched in 10.2.
When you close the view, it doesn't shrink down to it's original position on the right third of the bottom navigation bar. Instead, it shrinks to the far left side of the screen, where the Library, For You, Browse, etc. buttons normally are.
Then, after maybe a half second, the collapsed Now Playing view pops back over to the right side where it belongs and the other buttons reappear.
It may be that Apple decided to change the Now Playing view to make it full screen. If that is the case, then they still need to fix the closing animation. But I'm inclined to believe the whole thing is a bug, as all the wasted space and the difficulty closing the Now Playing view make no sense from a design perspective. It's not a show-stopper bug by any means. But it is irritating since this is a new bug introduced in 10.2, was reported to Apple in beta 1, and still hasn't been fixed.
