Apologies for the confusion. I got it set up, and included apps like fb messenger and viber. The weird thing is, it doesn't work in fb messenger and in viber, sometimes it works and sometimes it doesn't.
I read it really does not work with FB messenger at the moment. What I did was download AOD Notify on Playstore and it only started to work from there. As far as I know, Messenger is the only one where it does not work at all.
