If you make a Cash App overdraft, the app will show a negative balance until it takes back the Cash App overdraft amount to clear the negative balance.
If you want to make a Cash App balance positive, you need to deposit funds to clear overdraft that’s equal to or exceed the negative balance.
Let me clear one thing, the users can’t spend more than they have in their Cash App balance. Your Cash App account becomes negative when retailers or sellers charge your account short or for the purchases you have made in the past.
If the available balance is insufficient to cover the charges, your Cash App balance goes into negative. And there is no overdraft limit.
