Alert and Automation Notifcations on iOS - What am I doing wrong?

Configuration
1

I’ve been unable to get alerts or automations (with notifications as the action) to actually fire on my iOS device.

Any recommendations as to what I’m doing wrong or should change?

Here’s an example of a test automation and an alert that I’ve set up. If I manually trigger the automation it works, however when the actual event happens (for either alert or automation) it does not send the notification to my phone.

alert:
  back_door:
  name: Back Door is open
  done_message: Back Door is closed
  entity_id: binary_sensor.back_door_open
  state: 'on'
  repeat: 3
  can_acknowledge: true
  skip_first: true
  notifiers:
     - ios_iphone_x


- id: '1234566789'
  alias: Alert - Drink Fridge Temp
  trigger:
  - above: '44'
    below: '38'
    entity_id: sensor.st814_drink_fridge_temperature
    platform: numeric_state
  condition: []
  action:
  - alias: ''
    data:
       data:
           push:
               category: GENERIC
       message: Drink Fridge Alert
    service: notify.ios_iphone_x
