The latest version 0.90.1483 is completely broken.

The app doesn't allow you to sign in, it doesn't even bring up the sign in menu or account details it just simply does not work.
It also has errors all over the place that fail to load my devices and images, due to the network - 'check network', but as you'll see when you receive this feedback form the network is working just fine and the app has access to it.

It's not working, I know this is a beta but I'm surprised an update that goes backwards in was pushed out.
