Canon Powershot PX does not playback videos on Iphone SE (2022)

[Wil_Tamis]

Hi, when I make a video with my  (new) Canon Powershot PX by using the Connect app for Mini PTZ Cam on an Iphone SE (2022), I can play back the photos, but I cannot playback the videos. Then the smartphone screen turns black, still has sound. Is there some settings item I can adjust? Any help well appreciated.

I am using the camera in research into nesting succes of raptors in The Netherlands

A minor addition, you can download the videos, then they play normally on the smartphone. But that is a workaround, that should be unnecessary.
