Thanks for getting back to us.
In cases where the app does not work after upgrading your OS, the first thing before anything else we'll have to try, is a reinstall.
We understand you prefer not to delete the app because you are abroad and you might not be able to download the app. So we hope you'll have the chance to be back so you can upgrade the app. If you are not planning on going back to where you downloaded the app, sign up here to be the first to know when we launch Spotify in your country.
Let us know if you have further questions. We'll be happy to help.
Have a nice day!
