Having a huge issue with whisper groups when im nested 1 child channel removed from the top parent channel it doesnt let me whisper up to that channel when i us whisper all parents I can see it attempt to do that but it doesnt succeed and give me a No Whisper Target Found Error. Someone is sitting in that channel so not having someone in the channel isn’t the issue. Same if I use the All Channel Group
Maybe you do not have permission to whisper to that person because your whisper power is lower than his needed whisper power.
When you set this user as single target and you still get that error, than it the mentioned case.
