Fortnite voice chat does not work ps4?

As you can see in the title, my voice chat does not work for fortnite. My headset otherwise works properly in eg parties. I can hear everyone else talking at fortnite, but they can't hear me. Have already restarted and the voice chat and push to talk, I have made several times off and on again. Still does not work. Can someone help me?

Can you hear them over the headset or over the TV?

Maybe you have set push-to-talk in the settings.

If so, just turn it off and you can talk again.
