Panoroof - sunshade

[Rutland]

Hi all - I’ve come back to the car in varying weather conditions from thunder and lightning to red hot sunshine to find the pano roof sunshade not in the position I left it in. I usually leave it half back so I’ve got lots of natural light in the car, but it seems to have the ability to close itself at will. Never opens further - just closes. 
im thinking there may be some relationship between the camera on the screen and the sunshade. Is thisthe case ? Do they auto close during certain weather ?

I can’t find any guidance in the owners manual.

Mine has done the same occasionaly .. but I think it might be operator error.......   not certain but I "think" its linked to the auto-close window system .. so if I hold the "lock" button too long it auto-closes even though the windows are all shut!  Probably wrong but that's what it seems like to me !!
