A shot in the dark - I had this problem a few years ago, and it apparently happened because I had unsubscribed from one of their mailing lists. (Mine was so bad that it was blocking every auto-mailed anything, including the physical D23 magazine. I had to contact D23 every quarter to get them to manually mail me one.)
On a lark, I resubscribed to every mailing list they offer (
ShopDisney, etc).

(There used to be a different global opt-out/opt-in button that I also toggled, but I don't know that it exists anymore.)
The next renewal, I got my first AP magnets. (I'd been an AP for maybe five years prior and had never received them.)
