Thanks Waleed, this should do it!
I had the same issue, go to phone setttings>notifacations>soundcloud select Allow Notifacations, and Set as Priority. If it doesnt apper in notifications bar retart soundcloud. Hope this helps
Settings > Apps & Notifications > SoundCloud > Notifications > Toggle it ON > and make sure that everything under 'Playback' is switched on and also remember to restart your phone to be sure that these changes take effect.
