My PayPal Pay in 3 purchase was denied or did not go through, why do I still have a pending authorisation shown in my PayPal activity?

If you don’t successfully make a purchase using PayPal Pay in 3, PayPal will automatically void the pending authorisation within 72 hours of placing the pre-authorisation hold.  Funds will not be taken from your card if the PayPal Pay in 3 transaction was not completed.
