Hi there,
If you check the link in the private area you’ll notice that the ‘New’ label still shows although it is set to 25 days. This product was posted in February.
I think it has to do with changing over from the Royal theme which was there to the new Xstore one as the Royal theme had a manual label button for ‘New’ on each product.
Can you check please? You have the back end logins too.
