"In a retrospective measure to restore balance to some apps affected by a DRM bug that would render them unusable, Apple has begun removing negative reviews from App Store apps that have been unfairly discriminated against by users, wiping the slate clean in most cases.\r\n\r\nAs MacStories points out, Apple has wiped the negative reviews from apps including Instapaper, GoodReader and The Early Edition. A quick check shows that Please Stay Calm, Metronome+ and many other titles have seen reviews wiped too.\r\n\r\n\r\n\r\nLast night, Apple issued a statement\u00A0stating that the app corruption issue that has been plaguing the App Store had been corrected. Apple said it affected a \u2018small number of users\u2019, though we saw relatively widespread reports of the problem.\r\n\r\nThe statement from Apple:\r\nWe had a temporary issue that began yesterday with a server that generated DRM code for some apps being downloaded.\r\n\r\nThe issue has been rectified and we don\u2019t expect it to occur again. Users who experienced an issue launching an app caused by this server bug can delete the effected app and re-download it.\r\nThe issue surrounded the packaging of apps with\u00A0Apple\u2019s FairPlay DRM. Developer\u2019s apps would crash immediately on launch, causing the users to believe it was a poor update.\u00A0It caused major problems for some developers as one-star reviews were submitted for an issue completely out of their control.\r\n\r\nInstapaper developer Marco Arment was first to notice the issue (his app Instapaper was one of the apps that saw many 1-star reviews), sharing his experience\u00A0in a blog post. Apple\u00A0began telling developers\u00A0that it was working on a fix earlier yesterday.\r\n\r\nIf you are finding that many of your apps are crashing when they open (and hadn't before), Apple recommends that you delete and re-download them from the App Store. It is also pushing the latest update for that app again, prompting you to update to a non-buggy version also.\r\n\r\n[Image Credit: Jon Rawlinson]"^^<http://www.w3.org/2001/XMLSchema#string>
