Every time I listen to some music on desktop app, there's a great chance that now playing activity on android willl disappear. I don't know if it's because of buggy Spotify Connect feature of if there's some other reason. I have never seen such annoying bug in any streaming service.

It's almost impossible to resume some music in Android app after some time of inactivity cause the playing activity will just disappear.

Here's the easiest way to reproduce the bug: open Android app, then start playing music on Windows app. Close Android app, after this close Windows app. Open Android app and you'll see that playing activity (mini player) just disappeared.

The solution could be pretty simple: when user opens Android app, restore playing activity based on playing history instead of spotify connect data.
