Can't change the App wireless data setting which automatically switches to off
I have encountered this problem several times. When a new app is installed and opened for the first time, it asks whether it's allowed to use the "WLAN & cellular data" which I selected allow. But it automatically switch back to off. Then I went to "Settings->Cellular" or find the App settings, trying to change the "wireless data" option to "WLAN & Cellular Data" manually. However, after leaving Settings, the system will automatically switch to "off" whenever I open the App again. I have tried reset the settings, deleting and redownloading the app (which sometimes works), restarting the iphone, but for some app, this problem persist. It is very frustrating.
