I too have experienced this. I'll play soundbyte "A" and 1/2 my players can hear it, the other half can't. When playing soundbyte "B", the players that heard A, may or may not hear B. The players that did not hear A the first time may or may not hear B. But soundbyte "C" can always be heard by everyone! I've also found that the soundbyte "C" (that can always be heard by all), are older uploads. This issue seems to happen with recently uploaded sounds. All the sounds I've uploaded are in the same format and produced the same way. This just started for us on or about 3/18/2021.
