Service bus integration - duplicate messages and only up

Hi everyone and congratulations for this plateform,

I have two problems with azure integration :

:white_check_mark:1: When i received an up message from my device the message is duplicated in the bus queue.

2: In the Azure service bus queue i only receive event type “UP” but when i look in “Device data” in
Chirpstack application i have all types of messages

I would like to know if I made a mistake in the configuration but I’ve been going in circles for a few days
Thank you in advance for your help

[EDIT] - The first point is resolved, i removed “backend=“azure_service_bus”” from the configuration “chirpstack-application-server.toml”. But I still only get the up messages on the bus queue :frowning:
