I work in Banking, and RBI (India's Banking Regulatory organization) has enforced stringent norms for UPI transactions behind the scenes, especially for chargebacks/disputes, to ensure that the UPI transactions are processed faster and easier by the Banks and intermediary processors, with the aim that customers get transparency and accountability in digital payments.

So stringent in fact, that RBI shut down PayTM Payments Bank which was most popular market leader in that sector, because PayTM flouted the mandated norms for digital payments and payments banking.

That is also beside the fact that UPI platform has high uptime and rarely faces any outages.
