Starbucks QR Code Failure

Hello, I was attempting to pay at the Starbucks in Vega Subayevleri Mall in Ankara Altındağ. I wanted to use the Metropoll QR code to pay at the cashier. But I was told that it wasn't possible and there was a problem with scanning the QR code, so they suggested using a different payment method. I told them I couldn't make the payment in that situation. It's surprising that a large company like Starbucks doesn't have a dedicated technical team to handle these kinds of issues. It's not exactly ideal to redirect people to another payment method. I kindly ask the appropriate authorities to take a look at this issue. Take care.
