I have had this site running for several months and its been on pause, so I decided to check in on it and refresh my memory.
Oddly enough, I noticed my Navbar has suddenly stopped appearing on the live site. It is a symbol that appears and did appear properly in both the designer and live site previously. Now it only shows in the editor and not in the live site. I deleted the element and replaced it and have unpublished/re-published with no luck.
Sorry that I wasn’t able to respond fast enough. You also could have rebuilt your nav inside of the existing symbol to save you time. Hope you got it sorted. I couldn’t find anything wrong with your nav in the designer unless there’s something you overlooked in terms of a hidden interaction. That happens to me sometimes.
