I have the same problem. Any good information from TMS support? it is critical to normal use
or please DEMO project, how to move a marker without jumping.
If you want to use Marker drag & drop it is recommended to use TTMSFNCLeaflet instead of TMS FNC Maps.
In TTMSFNCLeaflet, Markers have an additional Draggable boolean property to enable Leaflet JS native marker moving. Then use the OnMarkerDragEnd event to detect when a Marker moving has ended.
This is indeed currently a limitation of the TTMSFNCMaps component because only common mapping features are supported.
Service specific mapping features are only supported in the service specific components (i.e. TTMSFNCLeaflet).
We will have to investigate if there are solutions available to make service specific features available in TTMSFNCMaps.
