You can send push notifications and inbox messages in Journey Builder to create a sequence of messages, such as a welcome experience or an abandoned cart reminder.
Important Journey Builder push notifications are no longer
created in MobilePush. Instead, create your Journey Builder
push notifications without leaving Journey Builder.
Note If the APNS certificate associated with your app is expired, you can't
add messages for that app to activities until the certificate is
updated. Update your certificate in the iOS Provisioning
Portal and upload the updated
certificate in MobilePush Administration. If your app is provisioned
with iOS and Android, sends to Android devices through apps with
expired APNS certificates aren’t affected.
