iPhone 8 - My “notes” app is not giving me the function to scan documents. Please assist.

Hello CB1969-59,

Thank you for using Apple Support Communities.

To scan documents in the Notes app, you need to have iOS 14.0.1 or later installed on your iPhone. Go to Settings > General > About and check. If you do not have iOS 14.0.1 or later installed, you will need to take a look at this article to update your iPhone: Update your iPhone, iPad, or iPod touch - Apple Support

Once you have verified your iOS is updated, take a look at this support article and let us know what and where the process fails

Best regards.

At any point did you ever update Notes? And are you using iCloud for Notes?

Yes.
