Windows Phone App unusable.
The title resume it all.
1/ On my Lumia, it is very difficult to log in, very often it is impossible, the link connection simply doesn't work.
2/ The app crash a lot.
3/ Also, the app only show the web site in its mobile version, and it is a really a bad mobile version for mobile phone (it probably works better in tablets).
The Windows Phone App is just unusable. I am very sorry to have to say that because the web version is really great and it would help me a lot if I can use it 'on the road'.
