We've made some improvements to the WDR 360 VR app. In order to be able to use it, a new version of the app must be loaded; it can be found here in the Playstore under the name "WDR Dom 360" https://play.google.com/store/apps/details?id=de. WDR.Dom360.

The old version will no longer be developed. Have fun visiting Cologne Cathedral!
