Because I had some issue to activate Adguard Pro (cf. my previous post) I went through the issue and review my setup. I do not know exactly what I did to make it work but the ad now disappears at the launch of the application. You make my day!
I love this new Adguard Pro version. Even if I paid a lifetime Premium account I had no issue to pay the extra 0.99$. To be honest I will have paid 2$ for it. You did a great job! Keep the good work going!
