Open the dedicated Facebook profile from the Xamarin iOS app.

I'm trying to use deep linking to open certain profile pages in the Facebook app, but for now, this will only open my own profile. The general format has to be fb://profile/<id>

unfortunately, every time I use it I am directed to the page with the caption Profile Unavailable

. The specific example I'm using is the ID of my colleagues, so from my app, if I want to go to his page, I'll open the url for fb://profile/10206768458598300

. Is there a new format for searching profiles? I haven't found any other solution to open a Facebook profile from my app other than opening the actual web page by logging in and navigating to the person's actual profile URL.
