Iq_notify seems not working anymore

Hi folks,

I have the problem that iq_notify notifies only the first mobile_app in my group

notify:
  - platform: iq_notify # the platform to use
    name: familie       # alias name for notify.{name}
    time: 2             # time offset in which we assume someone "just left/arrived" or "is staying"
    pairs:              # a list of presence entities are corresponding notify services
      - entity: device_tracker.pixel_4a_mob 
        service: mobile_app_pixel_4a              
      - entity: device_tracker.redmi_note_7_mob
        service: mobile_app_redmi_note_7
      - entity: device_tracker.patriks_handy
        service: mobile_app_patriks_handy
      - entity: device_tracker.pixel_6_pro_mob 
        service: mobile_app_pixel_6_pro

I trigger an alert by an input_boolean and the only app that’s notified is the first in the list. (in my case the pixel_4a)

alert:
  terrassentuer_stosslueften:
    name: Stoßlüften
    title: Handlung nötig!
    message: Die Terrassentür sollte geschlossen werden
    entity_id: input_boolean.trigger_stosslueften
    state: "on"
    repeat: 15
    can_acknowledge: true
    skip_first: false
    notifiers:
      - familie
    data:
        mode: only_home

Does anybody have an idea what went wrong?
Last week everything worked quiet fine.
