When will the rest of Naruto Shippuden follow on Netflix?

More than 10 seasons are missing. Does anyone know when these appear?

Unfortunately, nothing is known yet. If it happens, we will only find out a few weeks in advance

Not known, may take longer.

Not known

But you can continue watching on tv now, dvd / bluray or crunchyroll

You can't say anything about it because it is not yet known. But if you absolutely want to look further, just get the DVDs.
