Multiple issues with the Ipad and Iphone app:

Ipad App:
Spotify does not remember login credentials and tos need to be accepted everytime.
App is slow.
User interface is really not up to standards, some examples: selection is unclear (no onclick event), slow selection, volume knob does not react well.

Iphone app:
After connecting and hitting 'services' a blank screen appears and nothing happens. It does not work.
