Hello Team,
We have used the post feature to send feature updates to iOS customers. (Enabled push notification)
Only a few of them have received notifications and most of them don't. (especially in terminated state/killed state)
But after opening the app, They could see the post.

iOS intercom SDK used 12.1.1. Tested in iPhone with OS Version 16.0.3
