Unfortunately this started after the March update, not the same issues as I have seen raised in the forums.
When trying to re launch Titanfall after exiting game play I receive a message asking,
Do you own this game or app?
If you have a game disc, insert it now (disc is already inserted) make sure you're signed into xbox live (I am signed in and all other apps register that I am logged in)
if you don't have the right for playing it, you need to try it (I have no idea what I am being asked to try)
you'll need to buy it at the Xbox Store. (0x87de07d1)
Not sure why I am getting this msg, re inserting the disc helps but issue returns each time I attempt to exit gameplay and relaunch. I have tried turning off/unplugging console but this did not help other than that I am apprehensive of trying other general fixes without specialist advise.
Hopefully this is helpful and any advise/information you can provide is appreciated.
