Netflix says 2021 but do you know when?
First it was in spring 2021, but the latest thing I've heard is December this year. I'm waiting longingly for it * - *
Unfortunately there's no exact start date yet.
The shooting of season 3 had to be stopped in 2020 at the beginning of Corona. From November on it was possible to shoot again. Since then there has been nothing new, except for a few casting news. So I think filming is still going on. And the series has already been confirmed for 2021, but a month or day is not known. Many are assuming December 2021, I think that you can count on it even earlier. But in the next few months there will definitely be nothing.
