Why does PayPal say you have insuffient funds?

PayPal may indicate insufficient funds if your linked bank account or debit/credit card does not have enough balance to cover the transaction. Additionally, if there are holds or restrictions on your account, or if the payment exceeds your available balance, you may see this message. It's also possible that your payment method is not set up correctly or is facing issues. To resolve this, check your account balance and payment settings.
