Right now Spotify does not "fully" support iOS 8 as it is still in its beta stages.
The app should be compatible with iOS 8 by the time of its final release this September.
I am currently using iOS 8 beta as well. I've had many problems, but using a beta you have to expect things not to work.
I understand that. Please read the full post. This is not iOS 8-related unless OP meant he has an iPhone 4S. If you look at the crash dump I posted, Spotify is doing too much crap in its startup method. You can't really blame iOS 8 for that when every other app I use is working totally fine, and this issue started happening out of nowhere.
I talked with the tech service on Twitter and they don't know how to fix it yet, for the user of ios 8 they hope that with the new beta release it will work, if the problem is still here, wait a new update of spotify or contact them, for Twitter it's @spotifycares
I have the same problem, again. It occured after a install to iOS 8 two weeks again. And then the problems started. I reinstalled iOS and it started to work again. Then for the second the problems started so removed the app and this fixed the problems! But now, for the third time I have the exact same problem.
Problem: Tries to start Spotify --> The app seems to be loading then quits without leaving the startup phase.
Nothing except a reinstall helps. It is maddening and I think I might go crazy. 😞
I am having the same problem. iOS 7.1.2 iPhone 4S Spotify 1.7.1 Spotify Premium user (for now)
I've tried reinstalling Spotify several times. With a fresh install I can sometimes open the app but if I sync any playlists or albums then the next time I want to use the app I tap the icon and see the Spotify splash startup screen and the app crashes before it finishes starting up.
My problem is almost exactly the same. I have tried restarting, reinstalling, and completely wiping my phone. When I reinstalled Spotify, it lets me enter my login information and then crashes. I am so annoyed!! I just got Spotify Premium too!
