I use Spotify in an iPad Pro (iOs 9.3.1). Spotify works well until your last update (5.5) when the music stops randomly, jumping and doing impossible to listening. I am tired with the hundred of problems and the poor support that you have for iOs. I saw the comments in the app store and I know that I'm not alone. So I'm sad, because I use Spotify for many years but you are close to lose a client.
