Can't add Matter device - iOS - multiple Thread credentials in Companion app. Can't select one to be used or delete obsolate ones

[hindseb]

The problem

It is not possible to add a matter device to the preferred network. The reason is that multiple Thread credentials were sent to the iOS companion app. Thus, multiple credentials are available and the iOS companion App does not use the correct one. It is impossible to select a preferred credential or delete obsolete credentials.
