Unlocking crashes App

Greets!
I have spotify on my iphone 6, iPad mini retina and iMac. I normally play music through Spotify osx desktop and control it from either iPhone or iPad however, when unlocking either one the app crashes. This happens frequently. The crash also happens when i unlock the device even if I'm not using it to control music on the desktop version of Spotify. 

Also had my friend sign up with Spotify and uses it only on iPhone 6s and has also crashed on unlock a few times. Anyone else having similar issues?
