Can you check if the array of this code display value:
$location = get_field('location');
If yes there’s value,
could you check the external link from google if it is present in the footer:
https://maps.googleapis.com/maps/api/js?key=YOUR-KEY
If yes, this link is present,
please also make sure the javascript acf map and maps.googleapis.com can be seen at your inspect element – Network tab.
Previously i have this issue, but when I check these steps. It display correctly.
