I have no idea how Nordic Track works, but that whole iFit operating system is absolutely garbage. Previously I had issues with the hardware of our NordicTrack and not being able to keep a consistent pace because the capacitive pad would randomly get 10 mph as an input. today, however i got a software bug after several new updates. The safety key is being reported as removed. When I put the safety key back, the overlay momentarily goes away, but it immediately comes back.
