On my iPhone, not only do I have invisible scrollbars, but when they do show up, it's in the middle of the screen. And not always exactly at the same spot. Someone said it's a bug, and goes away if you don't use 'reduce motion' under accessibility settings. But it's been around for several versions of iOS, so I don't know that it's a priority to fix.
