I think I have the same problem. With the articles loaded at first it seems to work (click on “buy on amazon” and you go to Amazon and you can see the url with the ASIN and your tag)
BUT, once you click on “load more” the tag disappears from the url, even in the articles you’ve clicked before. Yo need to reload de page to make it work again.
So, the bug seems to be that once you click on “load more” the tag disappears from the urls.
I don’t know if this is because I’m using the free version, but i couldn’t find anywhere anything saying this…
Thanks in advance
