Hi Andie
Congratulations on your award, even if it is not quite what you wanted. I would contact the Tribunal Service once you get the official notification to get the 'Statement of Reasons' - which will tell you how the decision was reached. It would help you to know why you received nothing for mobility - which might help when you are next reviewed.
