Landing gear retraction in PA-28R from Just Flight

Hi, I noticed that the landing gear is not retracted when pressing the “G” key, at least in the outside views. This happens when I start the flight in the runway and turned on. In cockpit, landing gear lights are off when I press G or move the control. Does someone have the same problem? Thanks.

EDITED: I solved it by changing to cold & dark and later ready to takeoff in the tablet. It could be related to “state saving” being activated or so.
