After upgrading to an iPad Mini 4, I cannot make in app purchases. Please help.

What happens when you try to do an in-app purchase ? If you are getting a message to contact iTunes Support then you will need to do so (these are user-to-user forums) :

- go to http://www.apple.com/support/itunes/ww

- click on your country's flag

- click on the Contact Support at the bottom of the left-hand column

- click on Contact iTunes Store Support on the right-hand side of the page
