WhatsApp voice calls drop after screen turns off

[RiBHUS]

Anyone facing this issue after the Beta released (first version itself).. you pick or place a WhatsApp call, and once the screen times, your voice doesn't carry to the other person and vice versa, till you unlock the phone. Has been quite irritating.

Not having this issue. Try turning optimization off for whatsapp in settings>apps>whatsapp>battery

I just noticed it now. My connection fails when i turn off the screen. It resumes immediately i turn it on.
