A new debit card cannot make a payment and sign up for autopay

[Moon2]

I lost my former debit card and got a new one. Now the new card cannot be used to make a payment and sign up for autopay. It said that the transaction was denied by the card issuer, but the card issuer said that there is no problem with my debit card.

When updating credit card info, make sure to do the following to avoid the common errors and glitches that sometimes occur with this fussy process:

1. Clear your browser's cache & cookies
2. Use incognito mode
3. Select "Manage My Card"
4. Select "replace card"
5. Type your address exactly as from your billing statement
6.  Don't use a space in the postal code
7.  Use ALL CAPS if necessary
8.  Type everything, not letting autofill complete any fields

Try using a different browser and incognito mode. Also try clearing your cache and cookies then reboot.

 @Moon2 : Just for clarity...this is Visa Debit or Mastercard Debit right? Not just a plain old debit card.

Make sure the address matches the billing address. No space in the postal code. Some even match case of everything.
