It should be possible to allow access to all files, or allow picking a single file. The weird intermediary where I need to first select that I don’t want to allow access to all files, then select the files I do want (the single file I’m posting/sending), then select that file again from the app’s custom picker from amongst the files I’ve previously shared with that app, is absolutely awful.
