Can 2 live feed audio is heard several seconds before video occurs.
Cam3, same problem.
Very annoying.
I have an older device where various apps have gotten into this situation I believe from using newer OS provided stuff for this or they are not aware of something they did and don’t know how to correct it. While others work fine.
But, the playback device has its own audio processing time and that can also be a problem if the device offers no way to adjust it.
If its the camera or device or whatever though I don’t know. It is definitely an annoying thing though 
I haven’t looked into that here since I leave the audio off so can’t verify it.
