I can’t whisper people cross-realm unless they whisper me first.
Explained below:
If I try to whisper “Example-Moonguard” from my character “Sender-Illidan” , I will receive the error message “No player named ‘Example’ is currently playing.” It is attempting to message ‘Example’ on the same realm as Sender.
I am well-aware with how to play wow and message across servers. This is straight up a bug, and not user error. This is a large complaint in the wow secret farming discord, as people are unable to message
