I have un installed and re installed to no avail I cannot go up or down.
For some reason they decided to change the altitude control from the right bumper to the A button. Have you tried hitting that yet?
You have to use the Jump button to fly up and the Left bumper to fly down. If your Jump is Left bumper, then I suggest trying different buttons until you find the right one. I think that it will likely be “X” on Bumper Jumper, but I cannot guarantee. Does this help?
