I applied the change; however, it still it doesn't meet the goal to bring the look back to how it was before upgrading to Pro 2.1.
Please take a look at this topic, I raised on January, related to this: https://theme.co/apex/forum/t/how-to-make-my-static-top-header-unshrinkable/21735:
... I want the nabvar to stay on the top of the page as soon as the scrolling reaches that point, but keeping the logo "unshrinkable".
My goal is to have this behaviour:
A. Initially, a hero banner on top with the navbar at the bottom of the page (see below)
B. After scrolling up until the navbar reaches the top of the page, I'd like keeping the nabvar static on top allowing it to shrink but making sure the Logo remains as shown below (maintaining its size and top/left margin) while the rest of the page scrolls up "underneath" the nabvar (see below)
