Automatic live view is not working correctly on amazon Fire

When having Alexa Show 5 live view works great. However I am having issue showing live view on amazon Fire 8HD even when switching to show mode. I tried to creat a command “When pressing door bell show me Front Doorbell” for some reason it sometime it works and sometimes it doesn’t. I know Alexa is not ring, however both developers need to sit and test this as it important for people to have some type of screen on the wall next or there front door to see who rang the doorbell before opening the door. Anybody can help me with this?
