Nobody says it anymore

I've heard it explained that "hey" used to be more of an urgent way to get someone's attention, rather than a casual "hello" like it is now, so it sounded rude to some older folks.
Question for the Spanish speakers in the room: Is there even another term equivalent to "you're welcome" other than de nada that people actually use? Not super familiar but Spanish seems like a language where "it's nothing" or "no problem" has almost completely replaced other phrases responding to thanks.
Asked honestly and noting cultural differences that may apply here - could be there's a more formal "you're welcome" Spanish phrase and I've just never heard it. 'Cause, you know, I don't live in a Spanish speaking place.
