Full screen streaming on Alexa not working for Stick Up Cam

Hi All, I have 6 Stick Up Cam Solar 3rd Gen, 2 Floodlight Cam Wired Plus and an Echo Show 15. When I ask Alexa to show one of the Floodlight cameras, the stream is displayed in full screen and I can stop it by saying "Alexa, Hide [camera name]". When I do the same with one of the Stick Up cams, the stream is displayed in a small window on the bottom right rather than in full screen. Side effect of this is I can't hide the camera stream unless I first, manually, enlarge it to full screem by pressing the 4 diverging arrows on the screen. Does anyone know how to show the stream in full screen also for the Stick Up Cams? EDIT: I have noticed if I give the order twice in a row, i.e. if I ask again to show the stick up camera when the small PIP stream is shown, then it shows it as full screen. But I can't seem to find a way to make it work in the Alexa routines :-( Thank you!
