WhatsApps payment feature is only available in India where they implemented the feature in alignment with the Indian UPI initiative.

Therefore I'd argue that this specific feature can hardly be seen as waiting for a global rollout.

Payments was also launched in Brasil, and Facebook are on record as saying they want to expand it to more countries.

It's standing on the shoulders of UPI in India. Do they also plan to bring India's UPI to rest of the world?
