I noticed from the browser console that “As of February 21st, 2024, google.maps.Marker is deprecated. Please use google.maps.marker.AdvancedMarkerElement instead. At this time, google.maps.Marker is not scheduled to be discontinued, but google.maps.marker.AdvancedMarkerElement is recommended over google.maps.Marker. While google.maps.Marker will continue to receive bug fixes for any major regressions, existing bugs in google.maps.Marker will not be addressed. At least 12 months notice will be given before support is discontinued.”
Are there plans of adding the Advanced Marker to Anvil?
