I had the same issue and can’t remember how exactly it fixed itself but Try this … When you're at main screen, hold down at same time + and - button. When you see P1 on the screen, hold down + button for 10-15 sec until you see the speed jump up to 60+ this might jolt the system to work
just got mine aswell, trying to figure out how to unlock the throttle but all the videos ive found havent worked. do you happen to know how?
