Unzipping progress on iOS is not working correctly

[jeffmon]

When unzipping a file and subscribing to the progress, on iOS, it goes from 0 to 0.99997 almost instantly..then after 30 seconds later, it goes to 1. On Android, it works beautifully, and as expected.

Here is my code:

  useEffect(() => {
    const zipSubscribe = subscribe(({ progress, filePath }) => {
      setZipProgress(progress);
      return () => {
        zipSubscribe.remove();
      };
    });
  });

Shouldn't the progress on iOS behave the same as on Android? Going from 0 to 1 gradually until completion?

This happens on an iOS simulator and a physical iPhone device.

Using the latest stable version of react-native: 0.63.4, and the latest version of react-native-zip-archive: 5.0.6

Thanks in advanced!
