I just today had a new track accepted for the Xbox One - Halo: The Master Chief Collection.
However, I'm unable to view the tracks for the title, nor am I able to upload an image for the game. I've also noticed that there's some new stuff around making friendlier URLs for games, and I'm wondering if the two are not playing together very well.
Clicking on the title just returns me to the main TG home page.
