Completionists who faced an issue with Quantum Break's "Media Baron" achievement on the XBOX One will be relieved to learn that the problem has been fixed and those who have beaten the goal will be receiving a notification when they next sign in.
The "Media Baron" achievement is awarded to players who discover all emails, presentations, TV shows, radios and posters within the game. On the XBOX One, it's worth 20G. For players trying to track down the documents, a guide can be found in the timeline menu which shows grey dots for undiscovered material.
The unlock issue was discussed both on the Remedy Forums and Reddit, but the announcement of the resolution was by Remedy's Head of PR, Thomas Puha. The problem was due to a server issue and not a problem with the title, but has since been corrected.

For the very, very few who had problems with @QuantumBreak Media Baron achievement not unlocking, this should work now.— Thomas Puha (@RiotRMD) November 11, 2016
The issue was a server side thing, not with the game, but it should be fixed now. This is the Xbox One version. #quantumbreak— Thomas Puha (@RiotRMD) November 11, 2016
