How to watch Naruto Shippúden further?

I watched the Naruto series on Netflix a year ago. After that, I couldn't use Netflix for a very long time. I started with Naruto Shippúden in February and finished 4 weeks ago… At least with the first 10 seasons. I have the problem that I don't know where I can get the rest of the seasons from.

I prefer the German version but would do without it if I had to. It is important to me

not as much exaggerated advertising as for example on TVknow.

Can you please recommend pages or apps to me (preferably several different ones)

Buy the manga in an emergency

Legal on TVnow, but free of charge with advertising

Or on Animes4you for free without advertising but illegally.

You can't get past advertising if you want free at TVnow as already mentioned in German but not without premium and on Crunchyroll you can watch advertising and in Japanese unless you pay 5 euro for a month

Use adblocker on tvnow

It does not work

Then Crunchyroll but only with a subscription what costs
