I am in Dubai. Why is there a GrabFood card on my Delivery apps page?

Because the page shows every app we connect to, and GrabFood works in South East Asia only: Singapore, Malaysia, Thailand, Vietnam, the Philippines, Indonesia, Cambodia and Myanmar. In the Gulf the cards that matter are Talabat, Deliveroo, Careem, noon and Keeta. Ignore the ones your region does not have. The Orders from delivery apps tab in the docs lists the apps by region.
