Nest Display dashboard being replaced with screensaver

Hi All

I have a nest display that I use to display a dashboard in my study. When I turn the light on the dashboard is cast, when I turn the light off I stop the casting.

Recently thought the dashboard dissappears and the display goes back to displaying photos from my albums. I can re-launch the dashboard by going to the media menu on the display and selecting “Home Assistant Lovelace” which takes me back to the dashboard.

I want the dashboard to stay there permanently though. Anything I can do to ensure this?

Thanks
