I’ve heard it’s a generational divide thing between “you’re welcome” and “no problem.” I’m an older millennial and tend to use “you’re welcome” in more formal settings and “no problem” in more casual settings.

I use “no worries” if someone is apologizing but sometimes I suppose if someone is thanking me for some slight inconvenience I’ll also use “no worries.”

I read an article that older generations think “no problem” is a rude replacement for “you’re welcome” which is funny because they mean the same thing. The thing you are telling the person they are welcome to is your help and time because it was not a problem.
