Display Product Thumbnail in Checkout-Page and Product-Page

 Hello,

i am having a question related to the thumbnails of the configured products. Currently it only shows in the "Cart"-Button, but on the check-out page i simply get an empty, white square.

I think it might be related to the SOBER theme that I am using. Does anybody know how i could potentially fix this? Maybe with a code snippet?

And something else (maybe not so important): Also on the product page the image does not get updated, when a user creates a product (eventhough it ticked the checkmark in the backend that it should get updated).

If anyone has a solution to this, I would highly appreciate help :-)

Best,

Dani
