I have the "Add wanted issues to my Atomic Avenue Wish List" checkbox checked.
I had purchased several comics from my wish list, so I updated the "Wanted" checks in ComicBase, deleted my wish list on Atomic Avenue, then saved my database to the cloud.
I've done this multiple times in the past, and usually the updated wishlist reappears on Atomic Avenue within a few minutes. This time it's been about 20 hours and it hasn't shown up. I saved my database to the cloud again just to make sure, but still no luck.
