Question: The wlan and cellular data are automatically turned off for some apps
For some apps, I tried to turn on the wlan and cellular data, but they would automatically be turned off. No matter what I tried, they just couldn’t be turned on. I tried to reboot the phone, and reinstall the app, but nothing worked. I don’t think it was the problem of the apps. Even the Find my Frineds app and the iBook app have this problem.
iPhone X, iOS 11.2.6
