I was able to resolve it by following some other instructions that hadn’t been working previously. Maybe some of the actions I took above helped to resolve it as the API key created earlier and entered according to the instructions below had not been working.
Enter the API key in the site.
- From the Dashboard, choose Appearance > Customize. (Or click Customize if it appears along the top of the page.)
- Click “Congregation Map Information” from the list of options on the left side of the page. It contains two boxes, one for your address and the other for your API key.
- Cut and paste the API key into the Google Maps API Key box.
- Click the left-pointing arrow at the top of the box, click the Publish button, and click the X to close the Customize menu.
