I lost my Citibank credit card. What is the fastest way to block it through the app or customer care to prevent misuse?

The 'minimum due' trap is real. Banks love it because they charge ~36-42% interest on the carried-forward amount. If you can't pay the full bill this month, pay at least 50% — anything below that and the interest eats the rewards of the next 6 months.
On the add-on card: yes, the primary cardholder is fully liable for all spends on the add-on. There is no separate credit limit or statement. So only issue it to someone you trust absolutely — spouse, parents. Not friends, not siblings you have money disputes with.
