Hey so I checked and I don't know what the problem is, but I am still having problems with the whole syncing/nook cloud situation. Since the topic switched to the Evernote app, I'll use that as an example.

The first image here shows the Evernote version I currently have, notice no "n" symbol indicating that it is a nook app.

The next pic is just the evernote version found in the nook store, which has the "n" symbol. This is just to verify that all nook apps do in fact carry the "n" symbol.

The last pic is me trying to update my NON-Nook version of Evernote in the playstore. The update downloads, and then it gives me that error message.

Luckily this is not the same thing happening with Spotify, since it is the nook version, but it refuses to remove itself from my tablet. Also the Twitter app also gives me the same error message, yet I don't even see it in the apps menu

No Idea what's going on here...but I need help lol
