Hello everyone, I have a problem.

I use MQTT engine 's tag.  
Its source from ignition test edge 's MQTT Transmission and local ignition server MQTT Distributor now, it can read/write.

I use other MQTT Publish now.  
it quality is good.  
but it can’t write.

I use MQTT Fx ,it Sparkplug Decoder have some problem.
