Different welcome messages sent to different users

Hello,

Our forum would like to update our custom welcome message. I’ve been creating some dummy accounts to test a new message, and strangely some of them receive the customised text and others receive the standard Discobot “Greetings” message:

Thanks for joining [forum], and welcome!

  • I’m only a robot, but our friendly staff are also here to help if you need to reach a person.
  • For safety reasons, we temporarily limit what new users can do. You’ll gain new abilities and badges as we get to know you.
  • We believe in civilized community behavior at all times.

Any thoughts on why this is happening?

Thanks
