Concerning album art: pushing on the art (or the PA logo when there is no art) has been a feature on previous versions, but alternatively you can press the three dots at the top right and select Album Art.
Also, there are selections for Album Art in the Settings tab, which includes automatic finding, don't remember what the defaults were but wouldn't hurt checking what your settings are, it should auto-generate when you are connected to WiFi or data. I've also found if I have missing art, it's easier and faster to go into the Album tabs (instead of tracks or artist) which will apply the art faster and to all of the tracks in the same album at once... This really helps when you have over 10k songs on your card!
