Same here. In the Cessna take off tutorial. Clicking through the prompts with the mouse bought back proper head movement. The prompts cannot be seen inside the HMD. But I did take off and land a Cessna first time without crashing so this issue is trivial to overcome for someone like me ;p. After further testing even after getting proper head movement in the tutorial I could not manipulate the cockpit properly. I will be using a monitor for the tutorials then.
