Usually this is due to adding a custom Google Maps API key to your account (as discussed here), but without enabling all of the necessary APIs. To verify,
- Log into our website and go to My Account
- Go to Integrations tab
- Go to App Services sub-tab
- Look for an entry there for Google Maps
If you find one there, to fix the problem you can either
- Remove the custom Maps integration (if you don’t think you need it - this is mainly meant for apps that require geocoding a large number of addresses)
If you’re getting this map error but don’t have a custom Google Maps configuration in the App Services section of your account settings, or have verified that the correct APIs are enabled with sufficient quota, please contact email@example.com so we can investigate further.
