One Ui 7 Extend Screen Broken

[recDNA]

One of my favorite functions in my tab s9 Ultra is the gorgeous extend screen function for use with my Windows computer. It worked perfectly before the One ui 7 update.

Now, on extend mode, the vertical field no longer fills the screen of my Tab. I now have an inch of unused space at the top of the tab screen.

I read setting wallpaper scaling to "fit screen" option would fix it but I can't even FIND wallpaper scaling. Besides, when not in extend screen mode the wallpaper fits perfectly. It is the original wallpaper that comes on Tab s9 ultra. I haven't changed it.

Can anybody help me with this issue?

Thanks!

Never mind... I finally reinstalled the second screen app from the Microsoft store and now the screen is full. I have no idea why the original app disappeared from my app list but whatever works... right? I have lost the floating disconnect button from the top of the screen but I can use Windows displays to disconnect.
