If you are not using the card, the bank may not include it on the latest statement, which causes the card to not be updated on the homepage.
Now you can mark the card as inactive or cancelled. So that you don't get a statement reminder. And once the latest statement has the card's transaction, it will auto-update to live again.
Inactive means the card is still valid but you are not using it thus the card statement doesn't have any data.
Cancelled means you have cancelled the card but you still want to keep the spending data in the Finory app.
How to mark it?
On the single card detail page, on the top right click the 3 dots, and select Mark as inactive or cancelled.
