Yes Bank's app did not support it for Visa credit cards as far as I know. It supported only Mastercard SecureCode. But now even that is gone in the IRIS app. Also Google Pay has a problem with my IndusInd credit card. I cannot add it/verify it as the OTP for verification never comes from IndusInd Bank for the CC (but Debit cards from IndusInd I could add). For my Legend CC, only the IndusMobile app works to scan and pay via BharatQR.
