Q. Why do we need TTL (Time To Live)? Why might an App push notification fail to deliver initially and require multiple retries until the TTL expires?

A. There are several reasons why APNs (App Push Notifications) may not be delivered on the first attempt, requiring multiple retries by FCM (Firebase Cloud Messaging) until the TTL (Time To Live) expires. Here are some common reasons:

• Network issues: Poor internet connectivity or network coverage can prevent APNs from reaching the device initially.
• App inactivity: If the app has been inactive for a prolonged period, the device may not immediately receive push notifications, prompting FCM to retry.
• Device turned off: Notifications cannot be delivered if the device is powered off; FCM retries until TTL expiration.
• APN certificate issues: Problems with the APN certificate (expired, revoked, misconfigured) can hinder delivery attempts.
• Unregistered device: If the user uninstalls the app or disables push notifications, FCM continues attempts until TTL expiration.
