Hi,
Will have to do some testing over the weekend but from what I remember if using the nfo created by EMM then I get the cert. flag. To be honest though I cannot say this is consistent and so may not be directly connected to <certification> I picked up on it as this is something that EMM adds to the nfo and MC does not, perhaps I jumpped the gun again.
It could just be skin related, let me get back to you.
Thanks.
