For you Anchoir, On the Wix Code Properties Window, have you press the + button to add an OnViewportEnter and a OnViewportLeave Event ?? Screen capture to help.
You will also need to copy and past the anchor and manually add the events for each single one of your pages, since we can’t attach an anchor to the header
When you will add the event, it will automatically put some lines of code in the ‘page’ section, wich you just have to delete since you already have the full code on the ‘Site’ section
I had the same issue but manage to make it work (proof) : www.kassyarts.com
Hope it is helping!
