Good afternoon pondelonge,
Welcome to the Apple Support Communities!
I understand you are trying to share notes that have scanned documents on Messenger and WhatsApp but the content can't be loaded. Can you provide some additional information about this?
- Are you using the Apple Notes app? Are you using the Apple Messages app or Facebook Messenger?
- What format are your scanned files?
- Have you tried exporting your notes as a PDF file to see if it is easier to access and read?
The resources below explain how to share and collaborate with Notes using iCloud. You may need to reach out to Facebook for help with their apps.
Use Notes on your iPhone, iPad, and iPod touch
Share your notes on your iPhone, iPad, iPod touch, or Mac
Use the Files app on your iPhone, iPad, or iPod touch
Take care.
