Hello Suyogya, please forgive me my english ??
I’ve got variable product.
I choose one of the possible variations.
Now I’ve got product in the cart, and I can see thumbnail (for example in footer default theme widget).
Everything is ok, but here’s thumbnail of default picture product, not thumbnail of chosen variation pic. But, when I click on that wrong thumbnail, I can see large correct picture.
That means only thumbnail is wrong.
I checked it with other widgets and plugins, here’s still issue.
Everything is ok when I turn on storefront theme (and others).
