Hi! I am having the same problem.
Search Console says that "aggregateRating" "review" fields are missing in my 3 products.
And also: "No international identifier has been provided, such as a GTIN, MPN, or ISBN"
If you can help me would be amazing.

Thanks in advance!
If you are using Shopify default review mechanic. Simply install the code, easy to follow tutorial: https://feedarmy.com/kb/shopify-microdata-for-google-shopping/
And have you installed the structured data? I have a helpful link in my previous post.
You can test the results here: https://search.google.com/test/rich-results
I have noticed you have helped some users with this issue. I went through different answers and guides, however still very lost.
Google Search Console is giving me lots of warnings:
Are you able to help me?
Thank you so much!
Check what the issues are, and resolve the individual issue.
For example if the issue is related to product identifiers, my code will not magically resolve it. You need to ensure you add bar codes in Shopify with the vendor value. Then my code will be able to show it.
My recommendation, step by step check what issues you have, check what you need to do to resolve it.
I tested the results and I have 2 Errors and and 5 Warnings as seen below. I don't know how and where to edit these issue and I'm hoping to receive a detailed instruction on how to do this.
It would be amazing if I could easily provide you with detailed instructions. I think everyone would love that. Unfortunately, the reality is different.
Each merchant has different settings and different issues.
If I need to write instructions to cover all potential issues, I would be writing a whole day. My volunteer support can only go so far.
So after installing the code and you have issues, either the code was not correctly installed or you have not added the required data.
If after this you still struggle, I do provide a service to assist you.
