Yes, I know that, I try it, but they often use only strojček, Slovakian is our close language and I can speak it very well. But when I put only strojček, it shows me even videos with machine - in English which shouldn't be shown. I put it in Slovakian, not in English. It shows me for example braids when I put braces. It is very strange. I look for videos about two hours and it is because of inapropriate showing videos. But thank you for your advice.
