[dash8aviate]

I'm on Google pixel 7 Pro and I have the app downloaded but I want to be able to set one background or one scene for my lock screen in my home screen so I press on set as background then only for lock screen and then I got to change my scene and then once I change my my saying it changes. My lock screen background too AE meant to not be able to do that or is it just broken? Thanks!
