iCloud storage billing question
Just wanted to check, Is billing monthly, or every 30 days?
I noticed the automated charges are occurring a day or two earlier each month over the last 3 months (December 19, 2022, January 17, February 16, 2023)
After you upgrade, your storage and features are available immediately,
and your monthly payment date reflects the purchase date for your plan.
