Expo Push Notifications not working on IOS phones

When I run “eas build”

I get:

Loaded “env” configuration for the “production” profile: no environment variables specified. Learn more: Environment variables and secrets in EAS Build - Expo Documentation
:heavy_check_mark: Using remote iOS credentials (Expo server)

I don’t understand this notice but I am wondering if anyone can tell me if this might be the reason my app can not get push notifications on IOS phones currently.

If it is the reason, How can I fix it?
