I googled this extensively but have found nothing
I noticed that as of last week, facebook live videos -- both for my profile and my pages -- have changed automatically to broadcast full screen.
It is a recent change, a couple weeks ago they were still square (1:1 aspect ratio).
I see that most others' live broadcasts are still square, and I would really like to switch mine back to be square.
Does anyone have any insight as to whether / how I might be able to achieve this?
