I've had spotify premium for a long time. However in the past few months I've been suffering from a very annoying issue. Every couple of songs the playback stops at the end of the song, however the play button itself does not change.
The only way to resume playback is to go back to a playlist and select a song.
Clicking the play/next/previous button has no effect. This issue occurs on any kind of playlist: my custom playlists, albums, etc. I use spotify on different systems and operating systems (windows, macOS, different windows) and the issue occurs on all of them. It happens for local play and also for remote play. Any combination of shuffle/repeat has no effect on this issue.
