I really don't know why it keeps saying No items found when i search for the location 'Sneek' and 20 km distance. I have another location 'Bolsward' within 10 km from Sneek.
Again, when I checked Google API key you registered and click on "Check API" button I can see the message "REQUEST_DENIED - This API project is not authorized to use this API.".
=> hidden link
Can you please make sure first that Google API key is configured correctly.
I didn't know what was going wrong and i Googled the error. It looks like the Directions API and Geocoding API were missing. I added them and now the API key works :). Maybe this needs to be added to the documentation?
