Recently I had a friend inquire about the discussion button that appears above your picture when you are on a group page.
He was a little confused, since when he clicked on the button nothing seemed to happen!
I answered him,
No worries [name]… I did that too.
The button is to switch back to a discussion if you click on the new poll button.
So it may be a bit of a confusing layout, but think of it as a back button.
Hope that helps!
