I have a Modbus TCP device connected to my Ignition gateway with two tag groups applied to various tags: the first polls at 1 minute, the second at 15 minutes. The issue is that tags in the 15 minute group never publish to my MQTT broker via MQTT Transmission, while the 1 minute tags publish fine. See screenshots below of both tag group configurations. (On the 15 minute group I even enabled "Include timestamp only changes" hoping that would resolve it but the behavior is the same whether it's enabled or disabled.)

My broker is EMQX, and the 15-minute tags simply never arrive at the broker, even when I can see them change in the Designer.

My transmitter target path starts 3 parents ahead of the folder my tags are in. My 1min and 15min tags are in the same folder.

Any IDEAS???
