Can Control Android From Windows, but Can't See Its Screen

Using the native Win x64 TeamViewer application on Windows 10.

Android (Samsung Galaxy S20) has the Host app installed, and is assigned to my TeamViewer account.

I am able to connect to the Android device with the Windows application, and can even 'control' it by scrolling around and clicking (I have the phone right next to me for trying this out, and I can see that I do in fact have full access when I click or whatever), but I can't actually see its screen (it's just black) within the Windows TeamViewer application. So, I have no idea where to click, or anything. lol

Any ideas about what might be causing this, or how to 'fix' it?

Thanks! :-)

p.s. Long-time TeamViewer user (over a decade I'm pretty sure).
