I've been using Evernote for many years (premium) and this is the first time I've experienced this error - running on the latest Android phone, Evernote version 8.8 beta1. No issues with my internet connection and all of my notes are set to Offline access. It seemed to be happening with only one of my notes, although, I have way too many notes to check them all.
I was finally able to access the note in question once I made a change & Sync'd it from my Windows machine.
Is this still a known issue?
