The crash keeps occur on iOS 10 GM, the candidate version of the beta software.
iOS 10 is launched in US as non-beta software today. Time might have arrived for your Dev team to publish an udate of the app because the crash will extend to an huge amount of users in the following days
I can confirm that the crash still happens in the official iOS 10 version that was released yesterday to the public. (Spotify 5.7.0.1055, iPhone 6 128GB, IOS 10.0.1)
With our latest Spotify for iOS update (version 6.5), this should now be resolved.
