MQTT Sparkplug B Store & Forward

Hi,

I have set up a MQTT Sparkplug B Publisher, which publishes data to a Cogent Datahub Sparkplug B broker. Communication works as expected, but I run into problems when testing the store & forward feature. When reestablishing communication I can see in Wireshark that the SF data is sent, but the data isn't processed by the broker. 

The Cogent Sparkplug B expects that incoming late messages is flagged as historical ("is_historical" = true, according to the Eclipse Sparkplug B specification). I cant see this flag in Wireshark and i think that is the cause of the problem.

The MQTT communication driver is installed with System Platform v2023 P01.

Does anyone in the community have experience with this?
