ESPThing plus (U.FL)

I just added a Sparkfun Thing plus into my working ESP-NOW network and while everything seems to initialise correctly, there is no response to other nodes in the network. Is there something different about the ESP32-WROOM-32UE on this board?

My problem. I was so deep in the software design I had forgotten the new board would have a new MAC address. Hopeless!
