To edit your delivery instructions or address on an active order, head to your order tracking page in the Wonder app. Click on View Order Details > Edit order > Change delivery information > then select your address to edit any of the information including your instructions. You can also select a different address as long as it is still within the same delivery range for the location where you originally placed your order. Click update to save and you're all set!
If you're not able to complete the above steps, it is possible your order is already in transit with a courier and it is too late to edit, or you placed an order with a local restaurant on the Wonder platform and cannot edit this via the app. If you need to update the address or delivery instructions for a local restaurant order, please contact customer support.
