Negative update since my last post:
Over the last 6 weeks, I have had the patience to change, one by one, many of the PDF's I had in some notes so they are viewed as attachments in a list.
To my disappointment, at some point, all of those PDF's have reverted back to a huge "Single Page" view, turning my notes into a useless mess again.
To add context, this happens when the notes are being viewed from my PC. When viewed from the cellular phone app, the PDF's appear as attachments, so no problems there.
Seriously Evernote can do better than this! I am so frustrated.
