When a product is free in WooCommerce, my users were able to download files from the shop page, now, when they clic on the download button in shop page, they get redirected to the single product page.
If my users clic on the download button in the single product page, they are able to download. The issue is only in the Shop page.
If I deactivate JetWoobuilder, your plugin works great, but if JetWoobuilder is active it stops working.
JetWooBuilder is now on version 1.7.6 and the issue remains.
