filter for App Store doesn’t function right

This only happen recently. In the past, App Store allow 4 filter option when doing search for apps. I can filter by relevant, popularity, rating and release date.

I am heavy user on filter by release date, so I know what are new app release or up coming new app

however I notice that since last week, the filter by release date is no more giving accurate filter. Why by the sort result from the filter didn’t reflect any more on release date.

in the pass. All the up coming release app will top the 1 first page after put on filter by release date… now, it seem that those old apps and game is occupied the page and the upcoming release app is no where to be found.
