Spotify Connect in Android app is very buggy and annoying.

Probelm 1: if you pause music on PC, wait 5-10min, then open Spotify on Android, you'll see that now playing activity is gone and you won't be able to resume music from the android app. 

Problem 2: sometimes you need to restart both Windows and Android apps to make Spotify Connect sync playback.

Problem 3: sometimes when you switch playback from the Android phone to Windows PC or vice versa, music just stops on both devices and playing activity disappears.

Problem 4: often when you skipping songs in Android app while the music is playing on Windows app, the now playing activity in Android app may just stop updating the information about now playing song or may stop working at all. Next song/Previous song/Play/Pause/Progressbar just stop working.

The worst thing is that there's no option to disable Spotify Connect. So first two issues are happening every single day and it makes the UX awful.
