Z Flip 3 Cover screen

[soap]

I recently had an issue where live wallpapers were not being applied to my home page but rather the small cover screen on the back of the phone. I fixed this issue by long pressing the check-mark symbol in the upper right corner when previewing the live wallpaper. Though I fixed the issue it was still nice to see that its possible for wallpapers to be added to the cover screen. Maybe a future app update can turn this into a feature?

I'm afraid I don't think that developers have control over which screen the live wallpaper is applied to, what you experienced was most likely a bug in the OS.
