My Spotify for Windows lags in playing, pausing, skipping, changing tracks. Once pause is pressed, there is a lag of around 20 seconds or so before the song will actually pause, and during this period the song progress is still moving forward in the play-bar. Sometimes the actual sound stops instantly (but song still appears to move forwards) and sometimes only at the end of the 20 seconds. During this period I can't do anything else, and after this period Spotify suddenly corrects itself (pauses and moves the song progress back to where it was paused). A similar thing happens with playing, skipping, and changing tracks.
This has happened to me before but then I think just fixed itself. Suddenly it's started happening to me again. Have tried logging out and in, uninstalling and reinstalling, all with no effect. Please help!
