While playing through my likes in shuffle mode on Android the playlist will completely stop working if it encounters a track that is 'Not Available'.
Even if you manually skip to the next song it is still paused with no way to start the music again.
A similar issue about autoplay has been posted before: https://community.soundcloud.com/android-230073/track-not-available-in-your-country-stops-autoplay-7419554
Hopefully something is in the works to make autoplay work more smoothly with unavailable tracks because right now it's completely broken. Thanks.
