Every thing works fine after put app in 2.4G network.

@DonGiovanni What changes have you made to make MatterAddDeviceExtensionRequestHandler commissionDevice be triggered?

My code is same like this: https://github.com/below/MatterSample

Hi there: I have same issue, I added MatterExtension and App group, but still get no trigger on commissionDevice, did I miss something here?@RobinGao

@RobinGao Hi there: I still can not get any response from commissionDevice. I make a http request when receive callback in commissionDevice. I added MatterExtension, I am not sure if I miss some configuration to do that.
