I'm not sure how you think you all know "when" your certificates are supposed to post.

We first applied for and got our card at the end of last May. Got the certificate it seemed right away (never thought it would be something I needed to remember so didn't pay a lot of attention). Edited to say I now remember applying on board, and it was around May 17, and got an answer very quickly. So I thought my renewal this year would also be at the mid-end of May. No. Then I thought it would be when my statement closed in June. No. My certificate came just a couple of weeks ago, on or about July 13 (it expires July 13 of next year), a full year and almost 2 months from the time of the one last year.
