Either ‘offers’, ‘review’ or ‘aggregateRating’ should be specified

Hi

I’ve got a website using WooCommerce that is getting Google Search Console errors saying: Either ‘offers’, ‘review’ or ‘aggregateRating’ should be specified

Here’s the full error email:

This seems to be showing for all the sites products.

I have tried the proposed solution here: https://www.checkerboard.com/web-development/fix-offers-review-aggregaterating-specified – However this didn’t work.

Any other ideas on how to fix this are much appreciated.
