iOS push notification

[lary]

Hello, I wanted to ask if there is a throttle on push notifications for iOS for FCM.

After killing the app, sometimes when I send multiple notifications to my iOS app in succession, the latest message might not appear as the latest push notification. It might take a few minutes before the latest one comes or it might not come at all.

In the Android app, it displays and updates all incoming notifications.

Thank you

There is no throttling in our code. It must be either Apple or Google.

Thank you for the reply. Sorry but I have more questions. 

For the content for the FCM,  1) is priority set? 2) if there is a way to edit this for ourselves?

For the logs to see if the push notifications were sent out, should we check our server logs to the device?
Thank you and sorry for any trouble caused
