Cannot upgrade my iCloud+ Plan
I am trying to upgrade my iCloud storage plan from 5GB to 50GB and when I try to buy the new plan. I keep on getting a pop-up saying, "Something went wrong, there was a problem upgrading you iCloud Plan. Try again later." How do I fix this? I have already tried to do this on my macbook, and have signed out of my Apple ID on my phone, but nothing seems to work.
