iCloud storage details are currently unavailable. Try again later.

Hi folks,

I have been trying to upgrade my iCloud storage plan for a week now and keep getting the following message.

I have tried signing out of iCloud and re-booting the phone - but the problem persists - in fact I can't seem to log out of iCloud.

When I try to sign out of iCloud, I get the message to turn off "Find My iPhone". I put in my password and I get a verification error (see below).

So I can't turn "Find my iPhone" off and hence logout of iCloud.

Is there an on-going issue with iCloud in the UK that I'm not aware of that could be causing this?

Any ideas on how to resolve this gratefully received.

iPhone 6 / 128Gb / iOS 9.1

Thanks in anticipation,

RB
