well the first achievement was Unlocked 11/20/2015
and the final achievement was unlocked 3/16/2016
so there has been ample time for the system to read recognize and sync the data, that also does not change the fact that THIS site does not have ANY kind of entry for the app whatsoever. as I stated in my initial post
actually I am pretty sure this is exactly where this post belongs, being that this is not only an issue but also a possible bug that an APP that give achievements is not being recognized by the scanners, nor has an entry in the app listings.
Status changed from 'Logged' to 'Resolved' - Sorry for the inconvenience but it's added now. That app was in our blacklist. It was likely confused for the NBC app on the Xbox 360 which doesn't have achievements. This app will now sync up for others as well.
