Shader not automatically instancing nor gives option to in 5.6+

Unity Engine

Hello,
I have used this shader from this thread:

Shader "Sprites/AlphaCutoff"
{
    Properties
    {
         _MainTex ("Sprite Texture", 2D) = "white" {}
         _CutOff ("Cutoff", Range (0, 1)) = 0.5
    }
    SubShader
    {
        Tags
        {
            "Queue"="Transparent"
            "IgnoreProjector"="True"
            "RenderType"="Transparent"
            "PreviewType"="Plane"
            "CanUseSpriteAtlas"="True"
        }
        Cull Off
        Lighting Off
        ZWrite Off
        Fog { Mode Off }
        Blend SrcAlpha OneMinusSrcAlpha
        Pass
        {
        CGPROGRAM
            #pragma vertex vert
            #pragma fragment frag
            #include "UnityCG.cginc"
          
            struct appdata_t
            {
                float4 vertex   : POSITION;
                float4 color    : COLOR;
                float2 texcoord : TEXCOORD0;
            };
            struct v2f
            {
                float4 vertex   : SV_POSITION;
                fixed4 color    : COLOR;
                half2 texcoord  : TEXCOORD0;
            };

            fixed _CutOff;
            v2f vert(appdata_t IN)
            {
                v2f OUT;
                OUT.vertex = UnityObjectToClipPos(IN.vertex);
                OUT.texcoord = IN.texcoord;
                OUT.color = IN.color;
                return OUT;
            }
            sampler2D _MainTex;
            fixed4 frag(v2f IN) : COLOR
            {
                fixed4 tex = tex2D(_MainTex, IN.texcoord);
                if (tex.a > _CutOff) {
                    tex.a = 1;
                    return tex * IN.color;                    
                } else {
                    return 0;
                }
            }
        ENDCG
        }
    }
}

The code works as expected in uGUI, but Shader Instancing does not work as of 5.6. My shader-fu is weak, so if anybody can help out that would be greatly appreciated.

Thank you,
Ryan

Check this page : Unity - Manual: GPU instancing
There is an example that shows how to add instancing to your shader.

Thanks for the quick reply sylon, unfortunately, that solution does not work for Canvas elements. The new search resulted in this solution which seems to be working.
