Appfigures, a rating information platform that found out the disappearance of large-scale ratings in the App Store, said, ` ` Over 22 million reviews have disappeared from October 23 to 24, '' October 28, 2019 Announced on the day.

The graph below shows the transition of the total number of App Store reviews worldwide. From around October 23, we can see that the number of cases has decreased by more than 35%.



One app that was noticeably affected was Hulu, a streaming service, with 95% of reviews on the US App Store disappeared.



In addition, storage service Dropbox and mobile banking application

Chase Mobile have also lost 85% of reviews.

This bug has occurred in all 155 countries around the world where the App Store provides services, but the most serious damage occurred in the United States, and about 10 million reviews disappeared. China, the UK, South Korea, Russia and Australia were also the second most damaged.

Appfigures has also published the top 25 of the most damaged apps. Starbucks lost the most ratings, dropping over 1.66 million, more than half of all ratings in the United States. Cashback app ibotta lost 98.63% of its rating.



Initially, although there was a suspicion that 'the app developer deleted reviews containing inconvenient ratings', Appfigures confirmed the breakdown of the ratings that disappeared, and the ratings from 1 to 5 stars were evenly distributed As it turned out that it had disappeared, the suspicion of the defect became thicker.



After that, Apple entered October 29 and told Appfigures that `` Apple is recognizing this issue as an error and restoring the rating of the affected app '', this case became a malfunction I officially acknowledged that it was due.



By restoring Apple's review, many of the ratings were restored at the time of writing, says Curtis Harvard, developer of Slopes app for skiers, ` ` Thankfully, this problem was fixed overnight. It seems that Slopes ’ratings have returned to the level before they plummeted.”
