On Chrome on my Android phone and Safari on my IPad putting the suffix 'mobile/html' results in 404 not found, as someone else has said.
Looks really good with the larger artwork and the little graph at the top is enough to confirm that it is playing (even if we have a problem further down the line). So +++
On the negatives, however, as others have pointed out, the shuffle/random button has gone - a for me that is a big loss - so can we have it back, please?
Also when "Now Playing" happens to be in a Playlist, the Playlist detail is is partially cut off at the bottom edge of the screen (Android mobile) with no obvious way to scroll or resize - (it only needs to be half a letter height further up);
And finally, on the "Now Playing" pane, we seem to have lost access to the tone control. For some reason I need to alter the tone slightly when playing through my Bluetooth soundbar and I cannot fine this tucked away anywhere else (though I am willing to be corrected on this).
Great feature works well +++
Now much faster and smoother+++
We seem to have lost the "spanner" which gave access to Debug. For many this may not be essential but I found it useful when checking to see just what has been going on.
This used to give quick access to Bluetooth settings/pairing etc. This seems to have gone completely (unless I have missed it somewhere). I found it useful (and used it frequently).
Really just a repeat of my "wishlist": a "Add Now Playing" to playlist button (on the now playing pane); a blank pane accessed from the three dots against individual tracks for free text (eg lyrics, sleeve notes etc); and, if technically possible, an "omit" from random play button.
