I don't understand this app. It kicked me out of my own account and won't let me back in. It just keeps saying 'Unknown error occurred'. And of course there's no way of ever getting any help from anywhere, and so all of my friends and messages are now lost. And I have no intention of starting a new account. I'm not going through this again. If this allowed me to give zero stars, that is what I would give it. But of course I'm forced to give at least one star. Even when it doesn't deserve it.
