The latest version Woocommerce 3.6.2. brings my Awin affiliate links still to the right landingpage from the button on category pages but goes to the homepages from the button on single product pages. It is the same deeplink on both buttons that I inserted in the external link field.
Ter are no problems with the affiliatelinks from other networks then Awin as far as I can see.
With the version 3.6.1 there are no problems of this kind.
The page I need help with: [log in to see the link]
