Notification to mobile app of integration alert not working

I started to set up alterts by integration “altert”. This works so far with single entities in combination with conditional cards on the dashboard. What is not working to get push notification to the mobile app. This is what I did:

alert:
  alert_no_internet_connection:
    name: no Internet - connection
    message: No Internet
    done_message: Connection Internet established.
    entity_id: binary_sensor.fritz_box_6591_cable_lgi_connection
    title: no Internet
    state: "off"
    repeat: 10
    can_acknowledge: true
    skip_first: false
    notifiers:
      - notify.mobile_app_mobile_phone1
      - notify.mobile_app_mobile_phone2

When I send a message via development tools to this service it is working.

What I am doing wrong?

or even easier, add both to a notify.group then list only that group
