Allow App Tracking in iOS Apps
To enable all features of the C-Learning iOS App it is necessary to allow App Tracking.
The app will ask for approval on first start after installation. If App Tracking is declined at this place the features of the app will be limited.
App Tracking can be allowed or declined at any time via the iOS settings. Search for “C-Learning App” in the settings and open it.
The marked switch on the following screenshot has to be set to “on”
