Manual Alarm Control Panel - Delay in receiving notifications in HA App

I just finished setting up Manual Alarm Control Panel and have the following test automation:

# Using sensor to trigger alarm

- alias: 'Trigger alarm while armed away'
trigger:
 - platform: state
   entity_id: binary_sensor.kitchen_motion
   to: 'on'
condition:
- condition: state
  entity_id: alarm_control_panel.home_alarm
  state: armed_away
action:
service: alarm_control_panel.alarm_trigger
entity_id: alarm_control_panel.home_alarm

#Sending notification when Alarm is trigged

- alias: 'Send notification when alarm triggered'
trigger:
- platform: state
  entity_id: alarm_control_panel.home_alarm
  to: 'triggered'
action:
- service: notify.ios_iphone1
  data:
    message: "Motion Detected!"

The problem is it takes about 10 to 15 seconds for the notification to popup in the HA app. All other automations that send notifications are nearly instant.

Anyone with a similar setup have this problem?
