Category score decreased after app listing's update

Hi guys,

After the update of app listing, the score of our app on app store decreases significantly. I’m pretty sure that the listing’s content is good enough and there’s almost nothing changed recently.

I used https://sasi.unionworks.co.uk/ to check the score.

I also conducted research and I saw that there’re many apps like mine - which have their app store’s score fallen. In contrast, there’re several apps whose scores get increased.

I’m wondering whether do I missing anything after the app listing update. It’s great if I can get help.

Thank you!
