The shortcut to boss only unlocks when boss HP Gauge falls under 1000. Final Form Boss has 900 HP and Fletcher only drops on S-Rank in easy and casual where people normally reset-farm in.

So as soon as you open the shortcut you need to reset the map.

Without the shortcut your fleet arrives under fuel/ammo penalty at the boss and most likely won't eve be able to S-Rank it.
