Wishlist access was actually re-added to tvOS 17.2 just a few days after the update went live, but there has been no way to access a wishlist on an iPhone or iPad updated to iOS 17.2 or iPadOS 17.2.

Um, Apple didn't "restore" anything. The wishlist was always still there in the iTunes Store app in the upper right corner. All you had to do was tap it. Apple just gave us another way to access it. We still can't add anything to the wishlist, though.
