React-Three-Fiber / Objects missing in the mobile version

Questions
1

I have made this test with <MeshPortalMaterial> but 2 objets are missing in the mobile version (the diamond and the star) because of this material :

<MeshRefractionMaterial
            bounces={1}
            aberrationStrength={0.01}
            envMap={texture}
            toneMapped={false}
          />

Is there specific parameters for mobile ?
