Good App that doesnt work!

[Update for 4.7.0]
In line with the pattern, the newest version is even worse. Upon upgrading now I cant log in at all. Thanks Vodafone! Another great implementation!

[Previous version]
The design and idea of the app is great, however the back-end rarely works. It is very unusual not to get the message that it is not working or cant connect right now.

I have had the app for almost 2 months now. It is rediculous and a complete waste.
