Where is the map meant to appear?

Hi @dreadedhamish, thanks for reaching WCMp Support!!

As you have configured the Google Map API, now vendor can set the location of their shop page via Dashboard >> Store Setting >> Store Location. You also have to add the “Vendor’s Store Location” widget, via Wp-admin >> Appearance >> Widget

Once this will be done, the location of the vendor can see in their own shop page, as you can see here – https://wcmpdemos.com/WCMp/vendor/emrata/

Let us know if you have any further query.
