It Is Correct To Spell It As "Your Welcome"

With the digital age, many folks keep trying to correct me whenever I type "Your Welcome" instead of "You're Welcome". I'll even correct Auto Correct, which changes the phrase to "You're Welcome".
Even some English teachers these days are unaware that "Your Welcome" is a correct spelling. They think You Are Welcome is You're Welcome, so typing or writing "Your Welcome" is incorrect. This is something that was lost over time from not having been taught thorough information on the topic in school.

even if true, language has changed.

It constantly changes but regardless, my point is to illustrate that something is correct which most people are aware of and think to be incorrect.
