Thank you for
reaching out on the community and telling us about your issue. I do apologize for the issues you're having. It is odd that both of you are having issues specifically with the credit cards and nothing else. I'm wondering here if they might just need to be deactivated/reactivated. Down below I'll put steps to see if we're able to get the accounts back up and running.
First thing I'll
recommend is to save a backup to revert back to just in case. You can find how
to do so down below.
Next we'll try
deactivating all of the accounts. You can do so by following the article listed
Once all the accounts are
deactivated go ahead and follow the article here on reconnecting the accounts.
