Hi @CoolJ, thanks for flagging this with us.
I’m really sorry to hear about these QR code payments being voided! This sounds like a really frustrating issue, but it's difficult to pinpoint why this might be happening without looking at your account with you.
In order to get this resolved as soon as possible, we recommend getting in touch with our phone Support Team so that you can troubleshoot in real-time. If they can't solve the issue, they'll also be able to file a bug report so that our Engineers can take a closer look.
If you haven't already, please reach out directly by logging into your Square account and heading here.
P.S. Welcome to the Seller Community ✨
