I am using the Blockchain.info API for an online shopping website. I have a problem in my Receive API: Payments from other wallets are working fine. Also, payments done by copying the address and sending payment to that address is working fine, but when a user sends payment from another Blockchain.info wallet using QR code (scanning the QR code via Blockchain App for Android), the index.php page remains as it is. Neither the .js file is called, nor the callback.php.
How can I still be notified of such payments?
