Your Available Cash is the amount of money in your bank available to cover your fund balances. If your Available Cash is less than your fund balances, you may not have enough cash in the bank to cover your funds and your upcoming expenses.
The simplest way to resolve this is to lower your fund balances. You can do that by tapping the slider icon above the list of funds and selecting “Adjust Fund Balances”. This will list all your funds where you can adjust balances. Funds are not directly tied to savings accounts or real dollars so their balances can be adjusted directly.
Another option is to increase the Available Cash by contributing more to Savings. This will lower your Weekly Spending Limit by the contribution amount which increases your Available Cash over time.
