Hi everyone, our product is developed using the UE4.27 engine and is packaged as an apk+obb file, with a total size of about 1.8GB. After releasing new versions to AppLab or any other testing channels, users have to update the entire 1.8GB each time.
However, I remember there was a period when incremental updates were possible, meaning users only needed to update the parts that had changed. But later, it became necessary to update the entire package every time.
