I see that my iBooks seems to be uploading my books to the cloud without keeping a copy on my local device. So when I reopen the app, I have to wait for the book to do finish downloading (which is a hassle if it is a 600 page pdf)
How can I prevent iBooks from deleting local book files and moving them to the cloud?
Is this related to “offload I used apps” switch? (it’s on for me)
