Q: Can't downgrade icloud storage from 200GB to 50GB

A week ago, I upgraded from 20GB (annual subscription) to 200GB (monthly) as my data was going over 20GB.

A new 50GB plan was released yesterday. I follow the instructions given on iCloud storage upgrades and downgrades - Apple Support , but at the last step, the "Done" button is grayed out. So I can't downgrade.

I have tried both from my Mac (Yosemite, 10.10.5) and iOS devices (ipad, iphone, on ios 8.4.1) and same goes everywhere.

I have a total of 23GB of icloud data, so there is no reason I can't downgrade to 50GB. The 200GB is overkill for me at this point.

Thanks for your help!
