Why don't my notes appear appear in Evernote but my audio does after I sync my wifi smartpen?
Since your notes are not uploading to Evernote and only your audio is being uploaded, it appears that an over-the-air update of the wifi smartpen firmware has caused the issue and can be corrected by doing a manual update of the firmware using the Livescribe Helper app. Please see one of these articles for steps on manually updating the smartpen:

After updating the smartpen firmware, try syncing again using Helper. This should get your notes uploaded and synced with your audio. Please let us know if this resolves your issue.
