App is not tracking correctly! Within my ideal sleep/wake times, but app says I'm NOT. When setting foot warmer for any duration, then making any other adjustment to the bed, the app subtracts about an hour or more from the time! We also have 2 hand contrlers. One keeps showing battery needs replacement every 2-3 days! Sometimez re-seating batteries helps, but it's a royal pain! Sleep Number technology leaves a lot to be desired for such an expensive product. Tech support hasn't been helpful.
