Unable to hear audio. Messenger has proven that it is unable to provide even audio service for people in Turkey calling to America. I've tried with numerous people and it's either that they can't hear me or I can't hear them. The audio works normally for like 15 seconds then it stops for like 20 seconds. It keeps alternating during the entire call. Recommend using WhatsApp as I've had little issues with it while being in Turkey and calling to America.
