MQTT Bridge QOS>0 Not Working

Hi, I run the Chirpstack Gateway Bridge on my RAK7258 gateways and use the “LoRa Network Server Type” as Chirpstack 3.x (Protobuf).

When I set the QOS>0 in the web interface setup for the MQTT bridge and test the gateway going offline then coming back online, the LoRa uplinks that were received during the offline time are not being sent to my Chirpstack network server in the cloud.

Has anyone gotten QOS>0 to work? I understand that using “Automatic Data Recovery” with the Semtech UDP protocol would have a similar effect when connecting it to a gateway bridge in the cloud, but I prefer to have the gateway bridge installed on the gateway.
