According to the Apple notification alert received in October 2024, the APNS server certificate update for production is scheduled for February 24, 2025.
Has this change been implemented, or is there a platform or method to verify whether this update has been applied in production?
If so, where can we check this?"
The new root certificate is already active in the APNs development environment. You can test that the new certificate is installed correctly by trying to send a development push notification to api.sandbox.push.apple.com:443
In the Production environment, the endpoint 17.188.172.30:443 has also been updated to use the new root certificate as well.
You can use whichever is more convenient for you to test.
