Mastery has completely stopped working on Xbox. Every time I take a railfan shot, it keeps saying ‘upload failed’. Mastery has also had a ton of issues. No matter what I do, none of the mastery challenges will complete. The game isn’t picking up that I’m doing the things mastery is wanting me to do. Another huge issue I found was that livery designer decals that are from mastery have suddenly stopped showing up in my decal list. I don’t know what’s going on with DTL right now, but this badly needs to get fixed. It’s getting really out of hand
This issue has been reported repeatedly, I'm also experiencing it. Doesn't seem like they are going to do anything about it soon, it's been like this since they released the new route.
I'm having the same problem. On a whim I downloaded the game on PC through gamepass. My profile carried over just fine. I could upload railshots and my mastery updated. Quit the game and went back to the xbox, still had the same issue of uploads failing and mastery not updating. This could be a work around, but sadly none of the new routes are available for the gamepass version of the TSW2. Not a solution, but maybe it might help the devs to figure out what's happening on the console side of things.
