WhatsApp calls are not recorded both ways

WhatsApp calls are not recorded both ways. It only records what I am saying and doesn’t record the incoming sound from the other person

I’m on trial and was checking this feature. I was really hoping that calls would be recorded both ways but it only records from the microphone I guess and if call is not on speaker, it doesn’t record it from the other person.

Hi
Could you please increase the volume to check if you can hear any sound from the other side?
