iCloud, wants me to update my payment details

Howdy Jess_meyer08,

I understand you're looking for assistance with updating your payment method for iCloud, so let's see if the following information helps.

For starters, are you seeing the notification appear within Settings to update your payment method, or did you receive an email requesting an update of your payment method? If you received an email, let's make sure this is a legitimate email to prevent a potential phishing attempt. For assistance with determining if this is a legitimate email, if you did receive an email, check out the following resource:

Identify legitimate emails from the App Store or iTunes Store

If you see that this is a legitimate request to update your payment method, let's first check if you're part of a Family Sharing group. If you are part of a Family Sharing group, you may need to contact the group organizer to update their payment method if you aren't the organizer. For assistance with updating your payment method, check out the steps of the following resource:

Change, add, or remove Apple ID payment methods

If you're not seeing an option to change your payment method, Contact Apple Support for additional help.

Cheers!
