Hi Artur,
Thank you for this.
I have tested your map again using Autocomplete to fill out the location and it is working correctly now.
You may have a look at your latest map (ID = 19) and it will show a test marker on Las Vegas itself and the address will be set to “Las Vegas, NV, United States” instead of the latitude and longitude of the marker (which is shown when you add the marker using the right click method).
Please can you test this from your end and let me know if you are still experiencing issues adding a marker using the autocomplete address method?
Thank you for your patience.
