Lag – Grab: Taxi Ride, Food Delivery Review

I'm using iPhone 6s on the latest version of the grab app, every time i ordered food and my order has been received by the driver, the app started to lag on doing anything, like typing messages, accessing others features, etc like laggy on every thing, after finishing the order, the app works normally. Please fix
