The user interface is littered with useless crap, the File menu goes back to this weird completely new different UI layout etc etc.
And the best part is that if the VPN goes temporarily down it fails to send/receive new emails until it has been restarted.
Let me say that again.
It fails at its core functionality if there's a glitch in the network and cannot send or receive emails. That's just a next level of incompetence.
