After the latest dev prev update, why isn't the notifiction center working or even sliding down?

[WPCentral Question]

After latest dev prev update. The notifiction center not working or even sliding down.

i did the latest developer's preview update for my lumia 720 and so far i experienced no bugs but suddenly my notification center stopped coming down when i slide and i get no notifications on top either. what should i do? i cant even see the battery life anymore because the notification center or the bar doesnt slide.

Have you tried a soft reset?

Hold volume down and the power button at the same time until the phone vibrates and the phone will restart. No data is erased.

Give that a go and see what happens.
