Device Tracker is not working

Device Tracker is not working. I’m not sure when it broke. I have WiFi room sensors that have a PIR for sensing motion. If I enable them, I get push notifications as I move around the house even with my WiFi enabled on my iPhone 11 Plus. Here is what I have in my Configuration.yaml file.

  host: !secret asus_ip
  username: !secret asus_username
  password: !secret asus_password

  - platform: asuswrt
    interval_seconds: 10
    consider_home: 60
      track_new_devices: true

All I have in my Configuration.yaml is mobile_app:
