2 way talk acts like a phone clall

When I activate the 2 way talk feature on live view with my ring doorbell 2, it treats it like a phone call and I can't hear the person at my door unless I hold my phone up to my ear. I can't see any options to change it to "speakerphone" so the audio comes through my phone's speaker. During playback of video, I can hear what I said and what they said perfectly fine through the speaker. How can I change this? My phone is a Galaxy s8 plus. My wife's iphone 11 doesn't have this problem.
