iTunes legacy RSS returning old data

Hi! I'm using iTunes Music legacy (WebObjects) RSS link to get daily New Releases and New Music.

Problem: this is returning frozen old data from 2016 (not updating).

Example RSS URL for US 100 New Releases items:

https://itunes.apple.com/WebObjects/MZStore.woa/wpa/MRSS/newreleases/sf=143441/limit=100/rss.xml

This is returning old data which never changes. All returned items were released in August 2016 (one year ago).

Example URL for New Music added to US iTunes store:

https://itunes.apple.com/WebObjects/MZStore.woa/wpa/MRSS/justadded/sf=143441/limit=100/explicit=true/rss.xml

This is also returning old data which never changes.

If we use the RSS Feed Generator URL, everything is updated, but this feed doesn't include "cover art" image URL for the item, which is necessary.

RSS Feed Generator: https://rss.itunes.apple.com/en-us

XML URL generated:

https://rss.itunes.apple.com/api/v1/us/itunes-music/recent-releases/100/explicit/xml

Another URL is used to get daily Top Songs, Top Albums and Top Music Videos. Working perfectly.

But I don't know how to get New Releases and New Music with that:

https://itunes.apple.com/us/rss/topsongs/limit=100/explicit=true/xml

Please, how can we make Legacy RSS to begin updating New Releases and New Music again?

Or how can we make RSS Feed Generator to include cover art image URL?

Or how can we use the last URL (that used for Top Songs) to get New Releases and New Music?

Thank you so much for helping in any way!
