Thank you, Tobias! Very precious!
I still have a little hickup: if I open a file on the iPad, let‘s say a photograph, in an app, let‘s say Affinity Photo - I do all the work on the pic- but now it becomes unclear- have I been working on a copy of the file which had been ‚sent‘ to the app? So how do I need to ‚save/export‘?
There is still sone fogginess around these concepts, at least for me.
Did you find best practices for your procedures?
