Missing company identity in manufacturer specific data send in advertising and scanning response in iOS.

Hi all,
We are using nRF Connect Application to discover Bluetooth device implemented on nRF52840 MCU. Company identity data is set within the manufacturer specific data sent for both advertising and scanning response sent out by the device. The scan data received by the application is missing the company identity information when the application is run on iOS whereas we receive this information on Android device. This issue is observed when the company ID is same in both advertising and scanning response data but does not show up when the different ID's are set for advertising and scanner response.

Should we do further investigation on the MCU side regarding this issue or is this something related to how iOS handles data over BLE?
Is there any solution to this issue?

We require both the advertising and scanner response to produce same company ID in the data received.

Hi Yuan, 
Could you try to test using other BLE scanner to see if you observer the same issue ? 
It could be that it's just the nRF Connect app act that way, skipping duplicated information.
