It did no such thing. It allowed you to stay alert to danger while performing another exploration task, and gave you an extra benefit to the tracking and foraging tasks. It also prevented you from getting lost in your favored terrain(s) which is far from the only exploration hazard.
Not the strongest ability, probably should have let you know more details about your quarry. But hey, at least it gave you something actually ranger-y to spend all those stupid spell slots on. And, if that was deemed not good enough? Fine, but at least bring back Primal Awareness from Tasha’s then.
Natural explorer should have been global ability (not being 100% dependent on DM charity) that gives you:
You can always stay alert to danger while doing other tasks,
You have advantage on Survival checks
You can use stealth while moving at normal pace, and with disadvantage while moving at fast pace.
Then if you just need to have favored terrains, all terrains should give global benefit that is most useful in that terrain.
