Doorbell Motion Detect Video Display Minimised on Echo Show 8

I have the latest Ring Doorbell Pro and Echo Show 8.When the doorbell is pressed, I get a full screen video feed on my Show 8. That’s fine.If I enable movement notifications, the video will only display minimised (picture in picture). This is not fit for purpose.I have tried everything including setting up routines but I cannot get the video to display full screen.I see that this issue has been previously reported on multiple occasions.Is there a fix?Is there a reliable Alexa command to maximise the video display?Thanks
