When you are about to make cash app payments, they’re instant and can’t be canceled. For confirmation whether your payment is successful, you may check-in your activity feed also with the cancel option. If you will ask to refund payment from the recipient, he/she has a privilege for it. For this, click the activity tab on home screen of the cash app, then choose payment in question, and there choose refund and press ok. In case of any queries, just join our Cash App Customer Service.
