Not sure if this is a bug but all my sites are showing this error:

Oops! Something went wrong.
This page didn't load Google Maps correctly. See the JavaScript console for technical details.

I have the API key is entered correctly.

From the Console:

[Warning] Google Maps JavaScript API has been loaded directly without a callback. This is not supported and can lead to race conditions and suboptimal performance. For supported loading patterns please see https://goo.gle/js-api-loading (js, line 209)

[Warning] Google Maps JavaScript API warning: NoApiKeys https://developers.google.com/maps/documentation/javascript/error-messages#no-api-keys (util.js, line 57)
