What happens if I don’t have enough money in my Parent Wallet when a contribution is set to occur?

No contribution will be made if you have insufficient funds in your parent wallet when your contribution is triggered. The record for that contribution date will be listed in your transaction history, which can be found by tapping on Transactions at the bottom of your screen. It will be listed as Insufficient Funds with $0.00 deducted.
