Hello all, I have a problem with the Speech Central app. When I open the application, the list of books and documents is empty. I tap the 'add file' button and add a PDF file from my files. I start reading it. When I close the app and reopen it, the list of books and documents is empty, as if I never added anything before. For some reason, Speech Central is deleting my documents when I close the app and reopen it. Has anyone encountered this issue? I have the latest iOS and iPhone 14.
