I have the same problem and it’s frustrating that I have requested this feature for more than 2 years from now to their support. They haven’t responded back or haven’t brought this feature. Due to this issue, I’m forced to move all my sites to Woocommerce. I’m even ready to pay an extra amount to access this feature. Due to this issue we are using a workaround solution where we create our own static product pages and Cart pages. Please Bring this feature ASAP, so we can continue in WIX!
PS : I’m running a startup called Brandbox where we help creators in India launch their own online stores. I have launched 8 Online stores from Wix and we’re on the path to scale it to 100K stores down the lane.
