Hi @JamieD and Webflow,
We have the exact same bug, causing Safari visitors not to be able to use our site at launch. Here’s our open forum question:
Haven’t received a support response yet either. I have an open bug bounty on Upwork to find a developer to try to figure it out.
In the meantime, I am considering building another nav panel for Safari users and using javascript to detect the browser and show it accordingly. It will be hack but will get them something in the meantime.
