I am a Spotify Premium member and I have the iPhone X running on IOS 11 and it is constantly pausing too. Any time i get a snapchat notification. It just pauses itself, so i can be driving and my phone will be in the well under the stereo and my music will be playing through the aux cable, if i get a snapchat notification it just pauses itself and i have to go on my phone whilst driving to press play again. Its really beginning to bug me. It's worse whenever i open snapchat. If i open snapchat with music playing it pauses itself, soi go back to spotify and unpause it, once i hop back on snapchat it pauses itself again. I do the same again and i'm lucky if it works on the 3rd time, its becoming a nightmare. You think apple would've tried to sort this by now. I can't take it much longer, especially whilst im driving.
