It was moved into a feedback thread as it’s not a bug.
As Explore does unlock at level 24, as per it’s programming, this is not a bug - so doesn’t go into a bug thread.
Feedback around why it shouldn’t be unlocked at level 24, and made available earlier for new players is feedback, as you mention, and was thus moved into a feedback thread.
If it wasn’t unlocking at level 24 or something was going wrong with it unlocking.. then it would be a bug thread.
