This is some updated information for this problem……..
It looks like Grow’s scripts are being deferred on your site; if you search “data-grow-initializer” when viewing your site’s source, you’ll see “defer” inside the script tag. It is still likely Litespeed Cache, since I don’t see any other optimization plugins at play. This javascript deferral is pulling Grow out of the <head>
section where it should be installed and causing connectivity issues.
