Hello, I have had the same issue.
A new cared was delivered to me. I used its number twice (once on amazon, once on a private transaction) and now I have received another Doordash active card check notification.
Thank you. I just don’t understand how this could have happened in such a short time and with the same active checker—which doesn’t seem to have affected only me. I wonder how is Doordash being used in that regard.
