Ring Video 4 choppy external audio

We just installed the Ring Video 4 and overall have been impressed with it. However, one thing that's a bit sub-par is the audio quality on the doorbell's speaker. I got to the door today just as one of the Smart Responses was kicking in and it sounded like a circa. 1998 mobile phone call with gaps every half-second. Am I doing something wrong? (Everything is up to date and the connection to wifi is very strong).
