Watts vs grade is wrong

I realize that Zwift may have been playing with physics around racing, but this is too wierd. With the latest update running on iOS, my power drops when i start up hill and increases going down. Cant spin at preffered 90 rpm goin downhill and have to shift higher 3 or 4 times to increase my watts and maintain speed on uphill grade. Power slider in settings is set to max. Shouldnt feel like im going into a lower and lower gear as i start to climb.

did you connect the trainer as Controllable?

It was hooked up correctly. The next update problem was resolved.
