It seems like it doesn’t attempt to balance fast enough. My board just falls over and accelerates wheel as its falling. The board rides perfectly fine though. I’ve seen 2 other people say they had this issue, but I cannot find any other information.

Magic Flywheel mode is finicky. I would suggest placing your board on something that has more friction and can help balance the board better first (I used a rug in my garage). Then hold the board so it’s almost balanced before engaging flywheel mode (to engage flywheel mode without the app, you can press the left sensor, right, left and right to engage it.). The key to getting flywheel to work is making sure the board is as balanced as possible before engaging, otherwise it’ll result in what you described. Good luck
