Does one know why I'm not going on air in my livestream from the ps4?

When I go live, the icon that I'm on air does not sound hidden, does one happen to know why?

Because twitch made a change weeks ago

if you want to stream over the ps4, this only works if you have activated the 2 factor authentication

Where can this be done?

In the setting, where to change the password

On the PlayStation or Twitch

In your twitch profile of course, where else
