Yesterday, on 25th November 2022, people in the Telegram group started to note that topping up of wallet apps like Revolut using Grab was no longer working. There wasn’t a formal announcement, but Grab updated a support document to clarify that they no longer supported payments to eWallets and Remittance services. The examples given are not exhaustive, but pretty much include most of the popular apps and services people use:

• Revolut
• YouTrip
• BigPay Singapore
• ShopeePay
• Lazada top-ups
• Amaze
• EZ-Link app
• Remitly
• Western Union

Users could previously top up their Grab to get up to 1.7% cashback (with one of these cards), then top up these other apps which do not accept Amex as a payment method, using GrabPay as a conduit for cashback. I have zero information on how the cashback is funded, but I’m hazarding a guess that it costs Grab some money for there to be cashback on Grab top ups, at least partially....
