Problem buying more iCloud storage.
Every time I try and purchase more iCloud storage whether its on my Macbook Pro or my iPhone, a screen pops up that states "Your request produced an error. [newNullResponse]". I'm pretty sure I go through all the right steps to purchase it. I go to system preferences, then iCloud, then Manage Storage on the bottom right of screen, and lastly I click Buy More Storage and then it says "Your request produced an error. [newNullResponse]". Is there anything I can do to fix this or can anyone help me out? Thanks!
