Hello,
In version 1.35 you had built a feature request for passing the AttributeCombination Sku value to the dataLayer but it doesn't seem to be working as expected.
If you look at this image, you'll see that the AttributeCombination SKU has a value of B-3 however this value is not being passed to the dataLayer, instead the Simple SKU value of B is being passed to the dataLayer.
We need the AttributeCombination Sku value to be passed to the dataLayer.
Hope this image clarifies the request.
Thanks
