Hello. I have a question regarding the standard iPadOS Books app. When I try to open a PDF in the standard iPadOS Books app using the sharing function from another app that works offline, the Books app displays the message, "Your iPad is offline. Books could not connect to the Bookstore. Please check your internet connection and try again," and I am unable to open the PDF. Can this problem be resolved by modifying the other app that works offline? Or is this a problem with the Books app itself?
