Solved: Notify IOS, Error executing script

Hello together
I have 3 IPhone with “Home Assistant Mobile APPS” with which I send my weather data to my cell phone via Home Assistant Messages. This has always worked so far. But now one of the phones doesn’t get any messages anymore and I get the following error message in the log:

Outsidetemperature Notify: Error executing script. Service not found for call_service at pos 3: Unable to find service notify.mobile_app_leonie_s_iphone

Error while executing automation automation.Outsidetemperature_notify: Unable to find service notify.mobile_app_leonie_s_iphone
  action:
    - service: notify.mobile_app_martin_s_iphone_11
      data_template:
        message: "Test"
        title: "Temperatur"
    - service: notify.mobile_app_margrit_s_iphone
      data_template:
        message: "Test"
        title: "Temperatur"
    - service: notify.mobile_app_leonie_s_iphone
      data_template:
        message: "Test"
        title: "Temperatur"

a new installation of the app has brought no success.

I was able to solve the problem. The daughter has renamed her IPhone.
