My Tab 2 has suddenly stopped automatically syncing to my email accounts. It will do it manually but not automatically. I've gone into settings to put email sync on automatic but it doesn't seem to take. I've tried uninstalling the email accounts and reinstalling, to no avail. Email accts are micrososft exhange, yahoo and gmail. Any ideas? I can't think of any new apps that I downloaded before this occurred. It just stopped. Thanks!
