Evernote will not sync on my HTC Flyer tablet, which is the primary device that I use Evernote on. It has not synced with the server since March of 2013. I also have Evernote installed on my Android phone, which appears to sync with no problems. When I try to access Sync Settings, Account Settings (size limit, format and server), I get the following error message: "Connection failed. This application requires network access. Enable mobile network or Wi-Fi to download data. However, I am connected to the Internet via Wi-Fi and can browse the web fine, and can even access my account on Evernote.com. Please help! I need my notes to be backed up.
