I have a few sites where the sticky header over scrolls on one page navigation. I brought it up in this thread Scrolling Not Accounting for Sticky Header but the JS no longer works.
Additionally, I have browsed multiple topics through the forums. We were told this was a known issue since 2017 and that you would be fixing it. It has been 3 years and no fix is in site. I spent $400 on your unlimited license because I love the flexibility, but I expected little issues like this to be fixed.
Here is a link of your team telling us it would be fixed in 2018 Sticky header overlaps 1 page content using section ID for nav .
