APNs server certificate update and how it affects my app

Hello,

I am seeking inputs on a recent news received from Apple on "Apple Push Notification service server certificate update". Link: https://developer.apple.com/news/?id=09za8wzy.

We have some apps which uses Firebase push notifcation and Amazon SNS services. Since these are managed services, isn't it the responsibility of provider server to update the root certificate. Need someone to confirm. What about the applications which uses local servers?
