Hi, I am aware it is now possible to use freehand polyline drawing on Map Viewer : https://www.esri.com/arcgis-blog/products/arcgis-online/data-management/5-tips-editing-map-viewer-20...
It would be really useful if this feature was made available in FieldMaps. Ornithology team require this feature with a stylus to quickly sketch flight lines of bird on a map. Currently the ability to add verticies is not adequate for their needs.
Thanks
Joe
