Video Doorbell not displaying full view on iPad but ok on iPhone

When viewing the video stream from my Wyze Video Doorbell on either of my iPads, only the top is shown.

When setting the detection zone, the full image is displayed.

Clicking this icon does nothing other than change the icon.



It does this with the screen rotation locked or unlocked.

The image is fine on my iPhone XS Max

Any suggestions to correct this?
