Good find - when the area treated polygon is mapped on Field Maps app, @simonstratford, paste in the NatureMapr link to the comments field of Field Maps app - very useful as an id and photo-point reference for the control polygon. See this screen recording for instructions. It can all be done now from the latest NatureMapr app update: https://drive.google.com/file/d/1vYwvqgma8oBk87oQbVBxe3jJ8WjamHBS/view?usp=sharing
