Okay, so I thought that maybe having the newer YouTube look had something to do with why I was able to add a custom thumbnail to my videos on Micrisoft Edge, when it wouldn't work on Chrome. But then I discovered that the button to go back to the classic look is gone.
Why did I have to get curious?! The Creator Studio, even with the new look, still looks exactly the same as with classic YouTube. So chances are the new look has nothing to do with why I can't upload thumbnails. So I guess I'm just stuck with this forever now.
