Under Theme Options, there are a lot of areas to contend with.

Updates

We will have setup your copy of Divi with the correct USERNAME and API KEY.

API Settings

The API Setting is if you are going to use Google Maps, if you are not going to use Google Map, untick ENQUEUE GOOGLE MAPS SCRIPT. There have been issues with this part of the plugin slowing down your website because you do not have a valid API key installed.
When you are ready to use Google Maps, you need to get an API key from them.
This is a good page on how to do this https://www.elegantthemes.com/blog/tips-tricks/google-maps-api-key.

The Rest of Divi

We are using Divi only to edit some pages on our site, as we transition to having a full Divi website. At this time there is nothing else that we need to contend with.
