I remember it being pretty useful on phone. Now, it can't even "like" a song when I'm driving and I want it to add a song to my Spotify favourites list. It could do a few months ago, now it refuses with "sorry there was a problem with the app".

I've had to resort to asking it to take a screenshot so I can go find the song later. Three quarters of the time it never saves the screenshot though, despite seeing the screen flash out of the corner of my eye.
