Multiple licenses

I believe this has been asked but I don’t clearly understand how to navigate having two licenses. I need my work in my macOS license to show up in my IOS license, how can that happen? why does that not happen? I travel and write and prefer to take my iPad vs my MacBook, and have so much work on my Mac that I need to have shared with my iPad. I am NOT technically savvy so I need an easy way to do this. thanks so much.

to be clear- I have not yet purchased an IOS license. I need to know I can sync my work between devices.

There is no connection between your license and your work. Your work is stored separately from the Scrivener application and can be moved anywhere you want. @November_Sierra’s link has all the details.
