Map Not Loading (Error)

Hi there. I’m getting an error on my website both backend and frontend. In place of the map, there’s a grey box that says Oops! Something went wrong.
This page didn’t load Google Maps correctly. See the JavaScript console for technical details.

On the backend, I can tell the map is starting to load because it’s there for just a second, and then is replaced by the grey box.

I also cannot enter a Starting City in the backend because the error exclamation marks block the text field.

I’m using a different theme for this one (my other site using this plugin is on Vantage and is working fine), so maybe it’s a theme conflict?

Here’s the frontend page: https://yournaturalchoice.ca/pharmacy-locator/

Help is appreciated. Thanks!
