Apple has quietly changed its App Store policies and is no longer permitting iOS devices running pre-release software to be used to write App Store reviews. When attempting to write a review from a device that has iOS 9 installed, a popup is displayed that tells users reviews can't be submitted while using beta software.
This is a much needed change that will prevent developers from having their App Store ratings and reviews affected by beta-related problems that are out of their control. As MacStories' Federico Vittici pointed out last week, negative App Store reviews left by beta testers have been an unaddressed issue for developers since Apple started providing beta software to public testers.

When beta software is released, some customers fault developers for apps that crash or do not function properly with beta features, leading them to leave negative App Store reviews even though there are months to go until apps need to be ready for the new software.
Following the release of the iOS 9 and OS X El Capitan public betas a week and a half ago, developers began seeing a huge uptick in negative reviews. Many of them took to Twitter to share 1 star reviews that included comments like "Broken with iOS 9.0," and it appears Apple finally took notice of the issue.
Gotta love 1-star reviews for iOS 9 Beta issues. https://t.co/6lrFn9cP65 — Paul Mayne (@paulmayne) July 11, 2015
iOS 8.4.1, a pre-release iOS build that is available only to developers, continues to allow App Store reviews to be left, so it appears this may be a change that affects only major software updates or software updates that have also been seeded to the public as part of Apple's public beta testing program.

I remember Overcast broke popovers for iOS 9 users and people started giving it negative reviews. Because they were running a beta OS. And that somehow means the developer is at fault.
One quite popular audiobook is on iTunes for $22, on Amazon it's two parts each for $14. Guess how many reviews complaining about the iTunes price (yes, $22 is so much more than 2 x $14). Idiots. And how is complaining about the price in a review useful to anyone? I can see the price. It's clearly advertised. You don't have to tell me in the review. Tell me about the product, the things that I cannot see from the product description.
If you willingly signed up and installed a buggy OS you shouldn't be able to have a negative impact on the app because it doesn't work on a buggy OS.
They state:
"Please keep in mind that you should not install beta software on production or business-critical systems. We strongly recommend installing beta software on a secondary system or device, or on a secondary partition on your Mac."
But people want new and shiny toys right now, ignore the warnings, and then only care about the inevitable problems when they arise.
