Hey guys, when testing to see about my Mobile informations with looking at userAgent and platform.
I first looked at my site from my Mobile Chrome navigator :

Then I had sent it into my messenger account and read it from there, and here is the result :

Isn't that cool !! So Messenger previous navigator give you more info then the Chrome or any navigator ! I should think that is mostly a vulnerability, no ? Or was made by purpose ?
(Sorry if my English is bad, I'm not really that good at it ...)
