Can't add anyone to Family Sharing
I set up Family Sharing and can get to the Manage Members page in System Preferences on my MacBook. But, when I try to add someone I get a message that says: "This operation cannot be completed at this time." That message is then replaced by one that says: "Add a payment method to enable Family Sharing."
The problem seems pretty obvious except my account has a payment method and has had the same one for at least 10 years. I have gone to iTunes and verified that my payment information is correct. I changed the payment method from PayPal to a valid credit card, went back to System Preferences on my MacBook, tried again and got the same result. So I went back and restored the PayPal information and got the same Family Sharing result.
I have tried adding members from my iPhone 6 with the same outcome.
My frustration comes from the fact that if I am supposed to indicate a payment method specifically for Family Sharing, there is no indication in the error message—or any place else I can find—as to where that might be done.
Any help would be appreciated.
BTW: This may be posted to the wrong community, but I couldn't find any other plausible place. I picked iCloud since that's were I go to set up Family Sharing.
