Interactive PyACI : Group Publish/subscribe with server and client not working properly ?

Question

Hello, 
 I am working with the Interactive PyACI (nRF_SDK_for_Mesh 4.0.0 with boards nRF52832). I followed the tutorial "demo_configuration" present in the doc folder. Every works fine, I can scan, provision, bind servers and clients. Now I want to have a set up where a server send "notification" and other boards, which are client I guess, will get the information = state change (with a genericOnOff). So I think that correspond to the last point of the tutorial : #### Publishing and subscribing @anchor pyaci_demo_configuration_starting_configuration_5_publishing. I did as said in the tutorial, It looks like server and client are well configured because I get all correct return message and the the Json file looks correct (see attach). But when I set the server with gc.set(True), the led on the server board turn on but nothing happen on the client board. Yet I suppose the led on the client board must turn on since in the tutorial it is written : "You should now be able to use the Generic OnOff client to change the state of the server and observe that the client also changes its state accordingly". Is it normal that nothing happen on the client board ? How can we make a proper publishing/subscribing to a group please ? :) 
 Wainting for an answer, Thank you very much !
