Mingle 1 Just wondering how challenges work when app isn't linked

So I log into app with email and then log into community via website and try and do mingle challenges. Did the minimum but no points awarded. Too messy doing this separately. Plus when I log in app via email it isn't linked on community. So log into community via Facebook not Google and comments are same as app but that is via Google email. It's crap let's face it in UK and Europe now
