I wonder if there is a way to update the price every time the user selects a variation so that he knows the total cost before he adds the variations to the cart
I hope you are doing well today. Unfortunately, the feature is not currently available.
Will you help us by giving us a screenshot to show where you want to display the total cost?
You can upload your screenshot here: https://paste.pics/ and post it on this thread.
It will help me to pass the great feature request to our development team.
