I’m also getting the “no document selected” error when I reopen the app after a while.
Or as I thought was happening: the app doesn’t remember what document you last had open.
Happy to try some things too if you need. I love this app!
One extra detail. If I then try to manually open the last open document I was using, it won’t work. I have to select another of my documents first, then go back, and then select the one I was using.
