If your verification information is in the correct format, the editor will definitely add you. There are only two reasons not to add you. One is that your verification information format is incorrect, and the editor doesn't know who it is, so he refuses to add it. One is that the editor is too busy to add or forget to add. Wait a little longer. If you don't add it tomorrow, you can try again. It's impossible for an editor not to add you.
