I have a sole account, free version of DB and am building a Free Mind mind map to tell the story of my friend who was abused since infancy. Using a Windows laptop. We want to be able to edit the .mm file and pass it back and forth, with the most recent saved version available. Do I need Business or Family to do this for the file to be updated when shared? At the moment, I only know how to save it to my DB. If the other side edits it and I go look, I just have my saved version without their changes. In my File Explorer there is no drop down share option. All the vids and Help I search give options I don't have and don't work. Surprising given how long DB has been around. In the real world, when I pull a file from a folder in a cabinet, add to it and put it back, my changes are there for the next person. And theirs are plain to see for me when I come back. I'm surprised I can't sort that basic function of a filing system. What am I missing please? Thanks in advance.
