I have had my tenure reset to 0, I was due a 2 Years tenure in august however.
I have multiple friends who have had the same problem, but theirs has been fixed.
Why can't the Xbox "Engineers" Fix the problem for everyone, It's getting beyond a Joke.
I've even recovered my profile on my other 2 Consoles and the problem is still poking me in the eye.
Kind Regards, Nick.
