I've done setup of this FW(Version 2.1.1) and setup new restaurant. Once setup done I just configure google API key as per requirement.
I checked my restaurant Menu to add it into cart and for that I just added delivery postalcode as SE17 3QR(i.e. For Fleming road, London, England) store/delivery area also setup for London, England.
But unfortunately, it's giving me the error message "We couldn't locate the entered address/postcode, please enter a valid address/postcode.".
I gone through, tried everything which stated into: tastyigniter/TastyIgniter#124https://github.com/tastyigniter/TastyIgniter/issues/124
No Luck! Any help Please!
