Popup window not closing

[pors]

In a browser all works fine, I can login into spotify, and the popup window closes when completed. In a mobile app (iPhone with cordova) the login also works fine, but I have to close the popup manually by clicking "Done". The window is completely blank.

Any idea how to debug this?

BTW it does work in the emulator and also on a locally connected device (via USB). The problem exists only with a deployed version via TestFlight

Hey sorry for the late response -- not completely sure how to debug this. This seems like a very niche case -- where is the server running via your deployed version? Is the redirect URL, etc. set up properly?

Yeah everything works fine (redirect URL etc). I'm using the exact same setup for web, simulator, device with USB cable, and testflight version. All work except the testflight version. But I don't have a developer console for that...
