Control Center WiFi toggle doesnt disable WiFi
Following the iOS 11 release, I have found that I can no longer turn off WiFi using the WiFi symbol in the Control Center, instead all it does, is to disconnect me from the currently connected AP.
The Control Center's Mobile Data Toggle, however works, though it's Setting Screen equivalent suffers from a severe delayed reaction to screen press. This is still the case as of iOS 11.1.1
