I recently saw an email somewhere (which I now can't find) saying I was billed for optional iCloud storage. When I go into Settings->iCloud->Storage, it says I have 200GB total iCloud Storage, of which 170GB is free. When I then click Change Storage Plan, the screen tells me I am currently on the free plan of 5GB, but can upgrade to 200GB for $4.49/mth. How can I be on a 5GB plan when I have 200GB available??
