Wyze V3 Pro no sound

Any idea why Wyze V3 Pro isnt playing back sound? Everything worked just fine. All 3 of my Wyze V3 pro isn’t playing back sound. Very frustrating because i rely on these cameras to catch video and sound. Last month the cameras would not play an event when I click on the video clip; a few weeks before now backing out of scrolling through video would reset to the current time, and then last week camera clips do not show up unless you hit reset filters every time. This week there is no sound play back on video playback.
