Is MKI239A adapter compatible with MKI109V3 Motherboard?

Hi,

May I kindly clarify whether MKI239A adapter is compatible with MKI109V3 motherboard?

From MKI239A's website and Unico's GUI (device selection list), it seems that it is compatible.

But from MKI109V3's "Tools&Software" page and UM2116 (Sec.3 - Supported MEMS adapter boards), MKI239A is not shown in the list...

I am a bit confused...

 

In my case, when I chose the adapter, an error popped up, saying that "adapter has not been recognised, and the who_am_I register value does not match".
This scenario does not change even if I have updated the firmware of the motherboard to the latest (3.58.2) following the user manual UM2116 (2.2.1-2.2.2) of the motherboard, changed into another USB cable, and pushed the adapter into the socket as deep as possible. My Unico is also latest version for windows (9.16).
I also measured the voltage between VDD/VDDIO and GND when the adapter is inserted into the socket, and the resulting 1.8V makes sense according to the datasheet of the IMU (LSM6DSV).
