Blend shader not working in webGL build

Unity Engine
1

Hi ,

I am trying to use this blend shader in webGL build but its not working, It was working for android and iOS.
can anyone suggest what is the problem with this shader.

Shader "Blend 2 Textures, Simply Lit" { 
 
Properties {
    _Color ("Color", Color) = (1,1,1)
    _Blend ("Blend", Range (0,1)) = 0.5 
    _MainTex ("Texture 1", 2D) = "" 
    _Texture2 ("Texture 2", 2D) = ""
}
 
Category {
    
    Material {
        Ambient[_Color]
        Diffuse[_Color]
    }
 
    // iPhone 3GS and later
    SubShader {
        Pass {
            Lighting On
               ZWrite On
               Cull Off

            SetTexture[_MainTex]
            SetTexture[_Texture2] { 
                ConstantColor (0,0,0, [_Blend]) 
                Combine texture Lerp(constant) previous
            }
            SetTexture[_] {Combine previous * primary Double}
        }
    }
     Fallback "Diffuse"
}
 
}

Hi,

I found a solution in unity answers, This shader is working in webGL. Here is the link.

and here is the shader,

Shader "Custom/SimpleMix"
 {
     Properties
     {
         _MainTex ("Base (RGB)", 2D) = "white" {}
         _BlendTex ("_BlendTex", 2D) = "white" {}
         _Blend1 ("Blend between Base and Blend 1 textures", Range (0, 1) ) = 0 
     }
     SubShader
     {
         //Disabled tags because they were cause some weird issue to unity UI to get invisible.
         //Tags {"Queue"="Transparent" "IgnoreProjector"="True" "RenderType"="Transparent"}
         //LOD 200
         
         ZWrite On
         Cull Off
         
         CGPROGRAM
         #pragma surface surf Lambert
 
         sampler2D _MainTex;
         sampler2D _BlendTex;
         float _Blend1;
 
         struct Input
         {
             float2 uv_MainTex;
         };

         void surf (Input IN, inout SurfaceOutput o)
         {
            fixed4 mainCol = tex2D(_MainTex, IN.uv_MainTex);
            fixed4 texTwoCol = tex2D(_BlendTex, IN.uv_MainTex);                           

            fixed4 mainOutput = mainCol.rgba * (1.0 - (texTwoCol.a * _Blend1));
            fixed4 blendOutput = texTwoCol.rgba * texTwoCol.a * _Blend1;         

            o.Albedo = mainOutput.rgb + blendOutput.rgb;
            o.Alpha = mainOutput.a + blendOutput.a;
         }


         ENDCG
     } 
     FallBack "Diffuse"
 }
