I said intend for a reasonExcept that in the 2014 rules, not being seen is a requirement to become and remain hidden,

This part is largely still true, minus potentially the remain part (whether the remain is still true is basically this entire discussion)
at best they know the location where they last saw you, before you performed the Hide action, but you could have moved unnoticed sinceand the effect of being hidden is that creatures you were hidden from didn’t know your location. In the 2024 rules, not being seen is the effect of becoming hidden, and the rules are silent on the matter of if creatures know your location.
