In the Dropbox app on iPhone SE, I can open all my text files, but in some of them I do not get the Edit icon (looks like a cursor) at bottom left, so cannot edit them.
In others, I get the Edit icon at bottom left, and can edit them.
In both cases the text files are from the Notepad app on my Windows 10 PC.
When I cannot edit a text file, the settings and menus that I can call up do not seem to provide any solution.
Am I missing something?
