Thank you for the information all. The issue is in the hands of Microsoft’s Engineering Team at current - I’ll be sure to let you all know whenever we receive an update.
I appreciate you all providing your Gamertags, but I don’t believe these are required any more. When the issue is eventually addressed, it will be addressed for everybody experiencing the issue, irrespective of whether or not we have your Gamertags.
Thank you again, and sincerest apologies once more for the inconvenience. Admittedly I too am losing patience and want this to be resolved as soon as possible.
