Problem when stacking, plug too loose

  • Hello,

    I have a M5Stack FIRE and I want to stack a GPS module and the COM.LoRaWAN module.
    The GPS module holds great and other modules that are plugged in also hold well. The COM.LoRaWAN module also holds well when I plug it onto the GPS module, but I can't plug anything onto the COM.LoRaWAN module because it won't hold because the connector is not deep enough.
    Is this a known bug?
    What can be done to fix the problem?
