I've suddenly been having huge Gmail issues on my iPhone 5... Last weekend, it refused to refresh my email, giving me the server not responding error. So I removed and re-added the account on my iPhone, and it was fine. For a few days. Now, it will check for and download new messages, but won't send. They sit spinning, saying. "sending," until they just dump endlessly in the iPhone's Outbox with a red exclamation point next to them. I removed and re-added the account again, and it's still doing it. It's continuing to download new incoming emails as well. I do have two factor authentication turned on, but I know the application specific password. This is on my iPhone 5 (obviously with iOS 6), but I'm having no issues at all on my iPad 2 that's also running iOS 6. Anyone else see this? It's become massively frustrating that I can't consistently get my emails over the past week.
