@thyname - So, I don't exactly know why it works for me, but I can offer the steps I use.
First, I'm working on a Windows laptop, using Google Chrome browser.
When I want to @ someone, I type the @ sign and start typing the user name. A-goN starts auto-filling. When I see the name I want to @, I click on the blue highlighted box with their username. If you don't get the blue highlighted box, it does not work. Sometimes, if I'm sure I am typing the correct username, but the blue box does not appear, I will refresh the webpage and try again. Often, if I refresh the page, it will work when I try again.
After I click on their username in the blue box, it will turn the @ and username into black bold type. I then always tap the spacebar to insure I am not appending to the @name .
This procedure typically works for me, but not 100% of the time. Try it a few times to see if it works for you.
