No less than 3 tickets. Fragmented responses via email. Completely ineffective. Evernote is a service - you pay a subscription fee and are supposed to get the advertised features. When what you pay for doesn't work, you should be able to reach someone that can resolve the issue. That's service. That's NOT what Evernote is currently providing. An unfortunate trend in the tech industry.
What would be nice, is an acknowledgement, reply from Evernote staff in the forums, in this thread, that this is a known issue that will be resolved.
In the meantime, with limited help via chat, Evernote did provide the link to download the old version of Evernote for Android.

I uninstalled the new version and re-installed the old version. I am once again able to scan documents via my Android device, they are properly displayed as thumbnails in the notebook view, and are properly indexed via OCR and displayed among relevant search results.
Not sure why if it worked for a decade in the old app, that it's so difficult to program it to work correctly in the new version.
