Let’s break down the process into easy-to-follow steps.

1. Make the Crust:

• Preheat the oven to 325°F (160°C).
• Wrap heavy-duty foil around the bottom and sides of a 9-inch springform pan. Spray the inside of the pan lightly with nonstick cooking spray.
• In a medium bowl, stir together the graham cracker crumbs, melted butter, and sugar.   
• Press the mixture into the bottom and 1 inch up the sides of the springform pan.
• Bake until golden brown, 10 to 14 minutes.
• Cool completely on a wire rack, about 30 minutes.   

2. Make the Filling:

• In the bowl of a stand mixer fitted with the paddle attachment, beat the softened cream cheese on medium speed until no lumps remain, about 2 minutes.
• Add the sour cream, sugar, flour and salt. Beat until the batter is smooth and creamy, about 1 minute. Scrape down the sides and bottom of the bowl as needed.  
• Add the eggs one at a time and beat on low speed until just combined after each addition, scraping down the sides.
• Stir in vanilla.
• Fold in mango and strawberries.

3. Assemble and Chill.

• Pour the filling into the cooled crust.
• Place the pan into a baking sheet
• Bake at 350°F (180°C)
• Reduce heat to 325.
• Bake for 65 to 75 minutes
• Turn off the oven and let the cheesecake rest in the oven for 1 hour.
• Cool to room temperature, then refrigerate, uncovered, until chilled through, at least 4 hours.

4. Make the Glaze

• In another microwave-safe bowl, sprinkle gelatin over 3 tablespoons cold water; let stand 1 minute.
• Microwave on high 10-20 seconds or just until water is warm but not hot.
• Stir and let stand until gelatin is completely dissolved, about 1 minute. Cool until partially set.
• Meanwhile, place mango and remaining 1/2 cup water in a food processor; process until pureed.
• Stir in gelatin mixture; pour over filling.
• Refrigerate, loosely covered, overnight.

5. Release and Serve:

• Carefully run a thin knife or offset spatula around the edge of the cheesecake to loosen it from the pan.
• Release the sides of the springform pan.
• If desired, garnish with whipped cream, additional mango pieces, and strawberry slices.

These instructions are clear.
