Description
When using the https://github.com/geocoder-php/mapbox-provider with Drupal's geocoder module, Mapbox is unable to geocode US zip codes. I've tried both +5 and +9 zip codes. Mapbox also seems to have issues with searching for example Rockville, MD
(get results in New England 🤷♂️ ) yet searching for Rockville, Maryland
gets the expected results. When using more complete addresses, geocoding works.
When using the ArcGis Online provider, the above examples work flawlessly.
The Mapbox geocoder format guide suggests that US zip code (either five or nine digit) should work: https://docs.mapbox.com/help/troubleshooting/address-geocoding-format-guide/#zip-code-formatting
Has anyone else experienced similar problems with the Mapbox provider?
