Problems on Windows Phone

[RPerkins]

I've just got a Windows Phone updated to 8.1 and installed Spotify on it. However, on my starred playlist there's no sort function or filter as on the Android version. Also, if I simply unlock my phone or press the pin to go back to Spotify, it stops the playing track and goes back to the first song on the playlist. Is anybody else experiencing these problems?

Going to pop this over into the Other section since that is where windows phone issues tend to live.

Unfortunately the Windows phone app has always lacked a lot of the features of the other mainstream mobile apps.

Yeah I experience much the same thing, on top of my other issues with the app. Pretty close to cancelling my subscription tbh
