Ring Camera Automatically Launch Live View on Echo Show When Motion Detected

I have a Ring Spotlight Camera (not doorbell) and an Echo Show 5 with latest firmware/updates. I can't get the Echo Show to automatically display live view when the camera detects motion. The settings in the Alexa App are set to "announcement and live view" - and the Echo Show does make an announcement and will show live view if I ask it to with "Alexa, show front door" but I can't make it automatically display when motion is detected. I have deleted/reinstalled apps and disabled/re-enabled the Ring skill. Has anyone seen this issue / got any suggestions ? Many thanks.
