Ps4 Fortnite game chat is not working?

I have played normal Fortnite all at once I can't talk in game chat anymore but in PS4 parties my question is why it all tried different headset connected

Googled and more stuff

I only have it occasionally when I, as a ps4 player, play with PC players. Then it's usually enough for me when I start the PS4 again, leave the match and the group and then go back in… For me it was synonymous sometimes who is the Gruppenanfüherer…

So there are several possibilities

Hope it helps a bit
