The images in our rich push notifications won’t appear on iOS devices. What could be the reason?
Various reasons may cause this issue:
The app group’s identifier might be incorrect
You might have a problem with your app group registration. In this case, Xcode does not recognize the app group assigned in the Signing and Capabilities.
Or the app group string does not match the Signing and Capabilities, App Delegate, InsiderNotificationService and InsiderNotificationContent file. You should check these for typos.
You might have another push handler inside the project.
