I also have the same problem. Could be an issue on Chase's side, because I also tried creating a passkey through their Android app and I don't even see the "Add passkey" button there, even though it says that I can add and delete them through there. Update: I have tested disabling Enpass as passkey handler and leaving only the native Windows passkey manager, but I got the same results both with Brave and Firefox. This makes me believe again that the problem is on Chase's side.
