I have another email into the theme dev. I’ll let you know if I hear back.
It does seem to be something related to this theme with google maps because I tried a few other locators and all had the same issue.
I have also noted that if you go to the page with the map and then go to other pages, the map is properly hidden. I am wondering if there is some kind of CSS “hide-on-load function” that can be put in (I know that’s not the technical term).
That still of course doesn’t solve the issue with Chrome.
