Update 18 months after my original 1-star review. Still terrible. Still practically unusable, particularly with a mobile internet connection. Messages fail to send, or come through in a different order. The app hangs trying to switch conversations, or fails to find channels. And then it doesn't mark conversations as read after reading. Seriously, this is an embarrassment.

Worst app ever used! If I did not have to use it for work, I would not bother. Installed on my mobile, and it worked OK,for a whole. Then, it stopped updating. Unloaded it and reinstalled it again, 6 TIMES, and everything time I could not get past the login email address to be sent an email to get an email for my instant access. Can I give it more than one star?!?!

So. Bloody. Slow. It feels like everything is disconnected. Receive a notification, open the app, 45 mins later the message is finally visible, another 2 hours later and the notification finally clears. Why not pull the new message when the notification is received, and if you can't why does the request take so long? And why can't the notification in the app UI clear as soon as the message is seen, there's no need to wait for some round trip to a server to deal with that.
