Hello. I have recently subscribed to premium Mobile Security by avast, it is already activated on my Nexus 7. However, when I am trying to activate it on my phone which connected to the same google account, I got license invalid message. By checking out the email addresses of the device, the registered email on the nexus 7 is different than on phone, but in the phone was the primary email and on the tablet was the alternate email, but by the same google account. How should I fix this? thanks!
