After I upgraded Nokia Belle FP1, I cannot change the profiles from the power button anymore. What should I do?

The profiles can now be changed with the profile widget. The silent and general profiles can also be toggled in the task status bar. To add the profile widget to the home screen, tap and hold the home screen and select Add widget, scroll down and select the Profile.

In order to simplify the Power Menu, most of the profiles have been removed from the Power Menu.
