Hi! I’d love to help you with the issue where your deck appears empty even though you’ve input the cards. Just to clarify a bit more first—are you using the Gizmo app on your Windows device’s browser or through a separate app? Also, does the problem happen with all decks or just one specific deck?

In the meantime, here are some initial steps to try that often resolve card display issues:

1. Log out and back in: Sometimes reconnecting to your account refreshes the deck view.
2. Clear your browser cache: Cached data can occasionally interfere with updated content loading. For Windows WebKit-based browsers, clearing cache and cookies can resolve this.
3. Check your internet connection: Ensure you have a stable connection so the cards can sync properly.
4. Try accessing your cards from the Gizmo website: If you inputted cards via the app, checking the website directly at gizmo.ai might help confirm if the cards uploaded correctly.
5. Ensure the deck isn’t filtered or sorted in a way that hides cards: Sometimes settings within the deck can limit what is shown.

If you have already tried some of these, please let me know which ones, and I can guide you through more advanced troubleshooting or check for any current outages or updates that could affect card display.

Are you able to try those steps and share what you observe?
