Freedom on iPhone 6 plus not active when screen is locked.
I have Freedome installed on an iPhone 6 plus wth IOS 9.2.1. When the iPhone is on locked screen it seems Freedome is switched off and because of not being connected to the VPN I can not receive messages (Mail, Whatsapp etc.) When I unlock the iPhone, Freedome needs to make a connection first, that takes quite a bit of time and sometimes I need to do this manualyy. Very annoying, I assume it should be switched on all the time, even when the iPhone is in sleep modus?
Sometimes, when i close all applications that run in the background, the VPN switches on. Are there known apps that interfere with Freedome?
