Recently while on vacation, while I was offline, I discovered I couldn't open any of the links on my Android phone I had so carefully saved prior to leaving. The notes weren't even very big, just Bookmarks I had created using the Evernote Web clipper on my PC.
I searched the help today and discovered the following on the Access notes offline help page:
Full contents of a note are available from a mobile device if:
A note was originally created on that mobile device
Your device is connected to the Internet
You've recently viewed a note
You've set up offline notebooks on that device (paid subscription only)
Please restore the previous functionality that did not require me to have viewed a note while on-line.
