I am creating a group of custom fields containing a Google Maps field using Meta Box AIO. The issue is that the visual builder does not apply my API key but always uses the default hardcoded one in metabox: AIzaSyC1mUh87SGFyf133tpZQJa-s96p0tgnraQ
This is a very frustrating issue that is apparently well known: https://support.metabox.io/topic/google-maps-using-default-api-key-mb-settings-page-with-meta-box-groups/
The fix from that topic didn't help - it's always ignoring my API. I disabled all other plugins with no success. How can I solve this? Why is there a default API at all?
