Why does my payment information need to be updated when nothing has changed??

If that happened to me, I would add the correct payment method (which may duplicate the existing method) then delete the old method.

What does “it” mean exactly?

• What are the precise steps you took?
• What did you see exactly at each step?
• What worked?
• What failed?
• What error messages appeared?
• What hardware is involved?
• What operating system name and version?
• What other relevant details should we know?
