iPhone Connected Hearing Aid and WhatsApp call

Hi, Good morning

I am using Hearing aid(Beltone) connected with my IPhone 13 Pro Max though Bluetooth.

I am facing an issue while using WhatsApp call feature that caller cannot listen me but I can listen him.

This issue is only with WhatsApp call but not with regular cell phone call.

Please help me to solve this problem.

WhatsApp support told me that it’s OS issue, contact your IPhone support.
