Apple Card Interest

Not sure how or why that happen nor what may be a trigger-point.

There are Apple Card 'informational support' pages, with Apple info.

Some I've read through, had sought details to offer as advice; at times

that idea seemed helpful. However to read through and look, short of

calling someone/somewhere(?) I'd prefer to offer web links.

"Pay your Apple Card balance online. Once you add a bank account, you can

make payments toward your Apple Card balance in a supported web browser."

I've no Apple card; and with limited resources, prefer and hope to not

require use of one. (Pandemic aside; I've never been fan of amazon, etc.)

Although credit card allow level of protection not afforded by debit card.

Since you apparently answered your own question, there is no problem, but just wanted you to know:

We are not Apple or bank employees and this is not Apple support. So you need to check with the card issuer and/or Apple for an answer.

PS: There's an "Apple Card User Guide" (Table of Contents) online

just found, may be helpful to access most of these sections of use.
