Anchor Navigation Bar

Hi there!
I need to do an anchor navigation in my prototype, and I’ve tried with drivers. The scrolling part is okay with drivers. So when I scroll the indicator in the header is traveling to the right place. The interesting part is when I’ve tried to make a hotspot in the header and wanted to scroll my page down to the right place, and the indicator travelling. I’ve duplicated my artboard and set the current frame to the right place, but unfortunatelly it’s not working correctly. So it did the switch between the artboards, but the scrollable part stays exactly where it was.
Do you have any idea?
Thanks in advance.

That’s weird, I’m pretty sure that was how it should be done, I’ve tried myself with no luck either, so hopefully someone else will shed more light about this, I’m following this topic.
