In the sample app, navigate to the Edge tab.
Select a product, add the review information and click Submit Review.
In the console log search for this log message - Attaching event data (iOS) / New EventData for Event (Android) and check that ratingDate and ratingSource were attached correctly.

Once connected to Assurance, search for the Adobe Experience Platform Request Event in your session.
Check that the XDM data for the product.review event is correctly updated with the two new fields ratingDate and ratingSource.
