Issue with RuPay CC Payments Not Fetching on Merchant Soundbox – Need iOS App Suggestions

From the past few months, I've been making payments to some merchants using my BoB RuPay Credit Card via the BHIM app. However, I've noticed that their soundboxes (like Paytm and ICICI) often don’t fetch these transactions properly.

Has anyone else faced a similar issue?

I’m looking for a reliable app for iOS that supports fast payments with a RuPay credit card and ensures the transaction is fetched by the merchant's soundbox without requiring any hidden IDs or extra setup. Any recommendations?
