Realm Sync Session Not Working (React Native SDK)

Theres a feature in the docs to track upload and download progress. i want to create a loading screen that shows the download progress of the initial sync. Here’s the code in the docs:

useEffect(() => {
    const progressNotificationCallback = (transferred, transferable) => {
      // Do whatever with the values, set state, etc

    return () => realm.syncSession?.removeProgressNotification(progressNotificationCallback);
  }, [ ]);

Pretty straight forward, but when i run this, nothing happens. I’ve read some forums from a few years ago saying this was a known issue, especially with the download feature, but wanted to know when this will be fixed
