When adding a hyperlink in the product description I do this (which have worked on the old creator dashboard): Write the words I want the link to be attached to > mark the words > click the add link and add the link in the box > Here it just adds the words a second time without a link attached. If I DON'T write the words first and then first start with clicking the add link button and write in the words and add the link nothing happens at all.
Found this out while typing this. Temporary fix was to REWRITE the words! The text I used was originally copied from another product and this seemed to not work for the link system in the dashboard, very annoying.
