@username not working

I partially figured out what was going on. The @ won’t work with the username shown, but with the name shown on the user’s profile.

I’m sorry, I still have a question about this.

Seems like the @ link is only working when the user’s entire email address is used, as long as the ‘.’ is replaced by a ‘-‘ & the @ before the email platform is removed, so that ‘[email protected]’ becomes ‘admintest-com’ & is linkable when it’s ‘@admintest-com’
