They confirmed our speculations that you won't be able to spend the coins directly from your hardware wallet and the Ledger Live app with the card. You will be required to top up the card by manually sending funds from your LL app to the card's account address. Those coins will then become spendable with the debit card.
Not surprising, spending directly from your hardware sounds too good to be true and it means you need to bring your HW wallet along with the Ledger card.
