There's some people that you can't send audio whisper or reddot them.

If you send an audio whisper this say it's not possible because it's an old version or something else.
If they take the mic and you reddot them they can talk anyway

It's not an anti-reddot... if you reddot them before they take the mic they can't talk, but if they have the mic you can't stop them.

I was looking for this software for days and can't found them.
Anyone know about it?
