Platform doesn't collide with other platform

[Mista Void]

Hi guys,

I am new at phaser 3. I have a problem with collision

I don't know why my collider works fine with player and platforms

this.physics.add.collider(this.movingPlatform, this.player)

this.physics.add.collider(this.platforms, this.player)

but not with my platforms and moving platforms

this.physics.add.collider(this.platforms, this.movingPlatform)

here's how I made my platform and my new movingPlatform

// platforms

const platform = this.platforms.create(this.cameras.main.centerX, this.cameras.main.centerY + 1000, 'platform')

            .setOrigin(0.5, 0.5)

            .setScale(2.5)

            .setImmovable(true);

        

        const platformBody = platform.body;

        platformBody.updateFromGameObject();

// movingPlatforms

this.spawnPlatform = this.movingPlatform.create(this.cameras.main.centerX - 800, this.cameras.main.centerY + 920 - this.decrement, 'platform')

            .setOrigin(0.5, 0.5)

            .setScale(2.5)

            .setImmovable(true);

 

            const platformBody = this.spawnPlatform.body;

            platformBody.updateFromGameObject();

Please help me to solve this problem. your response would be helpful

thanks
