Where can I watch the 4th season of Haikyu?

The question is above. I really want to watch the fourth season of Haikyu! Does anyone know where you can watch it for free, because it's unfortunately not yet available on Netflix: /

Wakanim with subscription

Free of charge but only with subtitles at https://www.wakanim.tv/...ffel-4-omu. With a German synchro, it won't be out until April this year.

I already tried it at Wakanim, but it says that you have to pay 5 euro a month: /

Not for the fourth season. You only need an account, but no subscription.

On Wakanim, but so far only in Japanese with German subtitles
