UPDATE: Google Keep kicks butt all over EN for OCR of hand-printed notes. It is instantly indexed, and instantly searchable. But, it's Google Keep, and not Evernote. 😕
UPDATE: Image captured with Microsoft Office Lens (Android) then shared to EN was indexed successfully. As a bonus, the image was processed as a document should be. This is an acceptable workaround for now, but shouldn't EN's own document scanning workflow accomplish this?
UPDATE: The image which I attached to a new Note was indexed and can be found via search. None of the other approaches worked.
I have been experiencing no indexing in images of neatly written notes for the last several weeks. I have tried various approaches with no luck (EN Scan Document, Send image with Share Sheet on Android, and attach image to new Note.) No luck with Support Chat, but haven't yet opened a support ticket.
