clean_sess is not supported

[5HT]

received('CONNACK', State = #proto_state{clean_sess = true}) ->
    %%TODO: Send awaiting...
    {ok, State};

received('CONNACK', State = #proto_state{clean_sess = false}) ->
    %%TODO: Resume Session...
    {ok, State};

can you point me any guides how to implement this in client library?

@5HT it's documented here, do you know that it's not implemented? setting clean_sess = false doesn't appear to work from the testing I've done. Messages published with qos1 (retain false) while my client is offline are not received when the client reconnects. This is not the case when I do a standalone test with the same tests using the same broker and mosquitto_sub on the command line

Clean Session mechanism is normal in the latest emqtt implementation. Please try it.

We already landed a client based on emqx/emqtt in N2O:

Thanks a lot!!!
