I bought your plugin today. I have a geojson file stored in a web server. I created a new Map using your plugin and gave the geojson url. It is not showing anything. The same geojson displays fine with google geojson reader. The geojson file has only markers. But your plugin is not doing anything with the given URL. Initially it was .geojson extension. It didn’t work. I tried with .json extension. Even that is not working. API Key is and all fine.
What am I expected to do?
I have attached two files. The first one is the google console output after inputting the geojson content. The second is the URL integrated with your plugin. No problem with the permissions.
Please follow this guide tutorial https://wpgmp.flippercode.com/docs/how-to-insert-geo-json-url/
You can check here you have to paste the geo JSON URL at GeoJSON settings under add/manage map page. Please also mention your GEOJSON URL so we can check it at our end.
