Alongside the Store, you also get a brand new My Collection page, where you can view, organize and manage all the overlays you own in one single place.
I sure got a "new My Collection page"! Even though I own fifty cards, whenever I pull up the "All" page under the "Cards" section of "Collection," it comes up empty! (Similarly, the one NFT I own doesn't show up under the "My Trading Cards" page in DOLZ.) Oddly enough, most, if not all, of the cards I own DO show up under the "Previews" page in the store.
But since the cards I own have been showing up in the queue and playing in their entirety, I don't consider it a major issue.
