In my use case, I just want to turn on iCloud Drive on my MBP, iPad, and iPhone. I want it to be a simple file system where I can store files in my own folder structure. I’m thinking it doesn’t work like this though. Why, when I turn on iCloud Drive on my Mac does it then present various applications with checkboxes (Automator?). Can I not store a Pages document in my own folder and then browse to it in Pages on my iPad?
