@Thomas_Dus, How much music do you have when you start spotify on your phone? A fact: I have always known new IOS versions to be VERY BUGGY after they come out. Sometimes for a long time. Have you updated your IOS lately?

thanks for the advice. I did all the recommended steps and it worked absolutely fine ... until I switched on the off-line button in my songs (>3.600 songs). Even during the download I experienced the first crash. And even after restarting the app it crashed within the first song. After this I switched the off-line mode button back to off and the app works fine again. So, it seems clear that the problem is somewhere around the off-line mode. Either a general problem or in conjunction with the number of my songs (exceeding the maximum of 3.333 off-line songs). Is this a known problem?
