Firstly, I apologize if I shouldn't create a blog post for this problem. For me it seemed theeasiest way to find out a solution. Also, I didn't see anything related to it, but if something similar already exists, again, I apologize.
As you know, the chat entry point should look like in the first image.
But in fact, for me, it looks like in the 2nd one.
So, where did that little arrow which allows me to see other users online go?
