Signed up with F-Secure through my Virgin mobile account and put it on my iphone5 no problem, 12 months free. I then tried to put it on my wife's Windows phone and it came up with 30 days free, not 12 months. She deleted app. I then sent it to her iPad and the same thing happened so that app was deleted. Throughout these attempts it always said on my account 4 licences left. Can anyone explain the problem?
