Where are you from??
It could be the region is not compatible.
Have you been able to use the ap prior to this or did you just download the ap? I just got an "ap" update yesterday on my Iphone and there are no issues with it. I think that Apple sends the updates out at different times based on alphabetical or regional- I have family members that will get an update before me- sometimes up to a couple of days.
I find with a hard reset push top and lower button at the same time until it turns off usually works for mine
Same issue I have started a forum here and I invite you to post. If we get everyone together having the same issue hopefully they will release an update that fixes it!
