The Android app worked before the game came out, and for 2 days after. Now, it appears to be broken. My stats were showing up, but now they have reset (though the GRN website show my correct stats). I also cannot access the Career, Squad, or Heat Maps sections, as they are grayed out. Lastly, I can't access the sync part of Gunsmith. Basically, the app is totally useless to me at this point.
Also, the website says I got the 6 credits, but I can't use the app, so I have no idea if they are there.
I have emailed about this issue, and asked on Twitter. Both have gone unanswered, which is highly aggravating. I even had to email a second time because my question disappeared, even though I updated it almost it when I got the email telling me to.
