In iOS 10, I was able to forward directly from my app to its App Store ratings page by using the following link:
http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewContentsUserReviews?id=app_id_here&pageNumber=0&sortOrdering=2&type=Purple+Software&mt=8
However, in iOS 11 with its all-new App Store where the review page doesn't exist any longer, this seems to be broken now.
Does anyone know an alternative url that opens up the review creator page directly? Or does Apple want us to stop using such links?
