Disappearing settings
If we disable the option "Allow push notification" in the SIP Account section and disable it as well in the Network section, this option will disappear when we restart the linphone application.
After this it will be impossible to allow push notifications as well. I even re-installed the application without success.
Linphone version: 4.2.3 (SDK 4.3.3 - tags 4.3.3^0)
