GoogleBase - Google Shopping not working

Hello,
I have been attempting to activate GoogleBase so we can add our products to Google Shopping. This is the first time using GoogleBase, I usually manage feeds myself, but using a different platform.

I have followed the instructions very carefully, but my feed is not picking up any product information.
This is the xml and as you can see, it doesn't have anything but basic data in it: https://midwaleswater.co.uk/shop/index. ... oogle_base

Our website is www.midwaleswater.co.uk

Bumping as no replies.

OpenCart's built-in googlebase feed simply does not cut it for most people.

You should try one of the extensions available in the extension store.

Thank you
