Charles like to watch football he does not like to play it. The activities I did not like were getting up early to study communication skills. Having misst classes for three weeks, a doctor report is needed?

There are too many people, wellknown people, even public speakers who use "Thanks you" when someone compliments them. I was wandering - as my mother tongue is Hungarian and only my third language is English - wether the "Thanks you" is correct or not since I've heared it so many times. At highschool we were taught to say "Thank you" but is was already 25 years ago, there could have been changes in the English grammer, who knows... I am not an expert for sure. The influencers I follow through social media are all under 30, they must have fresh knowledge about the correct form of " Thanks you " or " Thank you ". I would be really glad if you could help me out because it makes me really confused. This expression is used each and every day, it's important to know the gramatically spotless form. Thank you
