Why does the wrong size variant appear in the cart on Prestige 1.2.0 theme?

I am having an ongoing issue where customers are adding one size to their cart and another one will appear after adding. For example, a customer wants a large and clicks add to cart, but a small pops up.

I have done research, talked to customer service , and even checked out the Discussion board, but I am not sure if my site would be able to have the same fixes others have found. I don’t want to do anything that maybe disrupt the website.

Theme: Prestige 1.2.0

Hello @lane201 ,

This happens because of a JS conflict. And conflict appears when you install/uninstall the apps or when you do customization in your store or when libraries update automatically. To confirm right click anywhere on the page → Click Inspect → Click console

Here you can check all the conflicts, Now try to fix them once conflicts fixed variant will start working automatically.

Thanks

Thanks! And once I am in Console, how exactly do I fix the conflicts?

I’ve checked a few items we’ve had this issue with and it’s looking like our Rebuy app might be the issue..

Unfortunately there is no guide available for it if you don’t know the code.
Alternatively try to revert the changes you did recently or install the fresh copy of the theme.

Thanks
