In my case, they were not necessarily a subscription, but my Insurance company and Power company had an option for AutoPay where I had to enter the information from my Virtual Card including account number, expiration data, and CVV. When I reviewed those sites, they alerted me that my CVV has changed and I needed to update them.
I did incorrectly use subscription as an example in my previous post as those that I had were actually a recurring payment by those companies. Thank you for the information you have provided and you are always spot on helping us fellow users.
Specifically for the OP question, I think it is clear that for Apple Pay, there is nothing that needs to be done. If you manually entered the card information including the CVV number, I would recommend reviewing those to see if further action is needed.
