I am trying to have google places autocomplete on an form-input. I keep getting following error:

["Google Maps JavaScript API error: OverQuotaMapError
https://developers.google.com/maps/documentation/javascript/error-messages#over-quota-map-error"]

However I think there are no restrictions in the Google Console API for the keys I use. Both Locations API and Maps Javascript API are enabled. Tried also making new api-key.

This fiddle (which code is provided by Google itself so should be ok) shows similar behaviour when a key is entered, so first replace YOUR_GOOGLE_KEY for a valid Google Key (I also used a completely unrestricted key...)

    <script src="https://maps.googleapis.com/maps/api/js?key=YOUR_GOOGLE_KEY&libraries=places&callback=initMap&solution_channel=GMP_QB_addressselection_v1_cA" async defer></script>

As soon as you start using the Address inputbox the above described error will appear.

My questions:

1. Can someone confirm the fiddle works with a proper google key (i.e. my google key is the problem...)?
2. If (1) shows the key is indeed the problem, what is wrong with my key?
