It might still keep counting up the time even if it's open but not visible.Posted by srylain the 2nd on 21 Mar 14 at 20:27 Xbox One achievements need to sync to the server before they unlock. If the server is down or Live is having problems, achievements won't unlock until everything is functional again. Just give it a while, and then check it again. Usually achievements that don't unlock when they're supposed to will just unlock at random times.Posted by srylain the 2nd on 24 Nov 14 at 12:22 Leave a comment
