IOS unable to send a FCM and trigger push notification after appCenter build:

Using FCM with Capacitor and trying to implement push notifications: Works fine in : Android IOS development IOS production only receive

Does not work: IOS production sending notifications

This is my post request to https://fcm.googleapis.com/fcm/send":

const body = {
    to: token,
    notification: {
      title: "Notification",
      body: `new notification`,
      sound: "default",
    },
    data: {
      sensitiveData: sensitiveData,
    },
    content-available: true,
    priority: "high",
  };
  await fetch(FCMUrl, {
    method: "POST",
    headers: {
      "Content-Type": "application/json",
      Authorization: `key=${process.env.REACT_APP_FIREBASE_SERVICE_KEY}`,
    },
    body: JSON.stringify(body),
  });

I have uploaded both development and production certificates to firebase console. Any ideas?
