When you have updated the album, you can look for the missing stickers, with two page entrances to find the cards you want:
- Click on the album set directly to view the missing stickers of each set.
- Click the "Missing Stickers" tab to toggle showing all your missing cards.
The above two methods can be selected according to your preference.
Click the Search button to see a list of other users who have this sticker, which is convenient for the next step of sticker trading to get your missing stickers.
