HUB - Google Maps is not working
If you see a gray color instead of Google Maps, it means you need to add your API key to the Theme Options.
1- Get your Google Maps API Key by following the steps in this article: https://developers.google.com/maps/documentation/javascript/get-api-key
2- Please make sure to activate the billing on your Google Cloud Project because Google requires that. They won't charge you unless you have 100k monthly visitors.
3- Go to Theme Options > API Keys and enter your API key. After entering the API Key, Google Maps will start working on your site.
If you still can't see the maps, try enabling Geocode API and Maps JavaScript API
