- Observed behavior

Open and Export the Document using Adobe Fill & Sign
Use the built-in file import feature in Adobe Fill & Sign to access documents from Apple Books, then utilize the share options to export the signed file.
Adobe Fill & Sign natively supports importing files directly from the device's file manager, which bridges the gap to cloud storage and local app folders like Apple Books.
Ensure the document you are trying to open is originally a PDF, as standard ebook formats (like ePub) cannot be signed or filled out.
Open the Adobe Fill & Sign app on your mobile device.
Tap the plus (+) sign prominently displayed on the main screen to start a new document session.
From the pop-up menu, select the 'Open File' option to browse your device's directories.
Navigate to the location where your Apple Books files are stored or use the file picker to locate and select the target PDF document.
Tap anywhere on the document to type text or use the pen icon to add your signature. Once finished, tap the 'Share' or 'Save' icon to export the completed PDF to your desired destination.

Frequently Asked Questions
Can I export the signed PDF back to Apple Books?
Yes, after filling and signing the document in your PDF editor, you can use your device's Share sheet and select 'Books' to save the completed PDF back into your Apple Books library.
Where does Adobe Fill & Sign save my completed documents?
Completed documents are automatically saved within the Adobe Fill & Sign app's recent files list. From there, you can permanently save them to your device's local storage or upload them to a cloud drive.
Can I edit existing text in a PDF using Adobe Fill & Sign?
No, Adobe Fill & Sign is designed strictly for adding text overlays to forms and inserting signatures. To modify or delete existing document text, you will need a comprehensive PDF editor like WPS Office or Adobe Acrobat.
Why can't I find my Apple Books document in the Open File menu?
Ensure that the document is actually saved in PDF format. eBooks saved in ePub format cannot be opened directly in PDF signature apps. You may also need to check your device settings to ensure the app has permission to access all files.
