Can't answer WhatsApp calls using Meta Gen2 Glasses

Hi I am using Gen 2 glasses paired with Honor Magic v5. I can initiate WhatsApp calls using Hey Meta but I can not answer a WhatsApp call using the glasses, Hey Meta Answer does not take the call, there is no response, also tapping on the side bar/temple does not trigger Meta AI. I tried all the steps recommended on the net including pairing, unpairing, disconnect/reconnect WhatsApp etc. Nothing worked so far. Also software is up to date. No issues experienced when answering phone calls. It is happening only with WhatsApp. Thanks in advance for the support.
