Yeah I am not sure why my status was changed. I have not gotten any letters or had any appointments from the VA since I was started on IU. It seems kind of arbitrary to be honest unless I was moved up to 100% from the 90% I was already on due to the IU rating. I have also had no earned income because my disability makes it hard for me to function outside my house. This letter was the only one I received saying I was no longer on IU and the only reason given is that the original decision was unmistakably erroneous and no other reason is given.
