Hello @amir1112
After carefully reviewing your case, it’s clear that we have diligently helped you resolve the issue you raised multiple times through different ways, including email and chat.??
Initially, you encountered the “Invalid Value [MPN]” error, which was caused by making direct changes in the Google Merchant Center and by assigning a blank value in the MPN field. Our team promptly intervened to rectify this issue and assist you in fixing it. Thereafter, you encountered a separate warning, “Limited Performance due to Missing Value [GTIN]”, which is unrelated to the previous “Invalid Value [MPN]” error.
Once you submit a product feed to Google Merchant Center then Google review your products and raises errors or warnings if they do not meet Google’s requirements. Your product feed must adhere to Google’s Product Data Specification requirements. The errors and warnings related to the product are enforced by Google but not by our plugin.
It’s important to note that our plugin’s primary function is to submit product feed to different marketing platforms by fetching it from your store.
Despite this, we remain committed to assisting you and providing clarification on the distinctions between MPN and GTIN attributes, as well as the reasons behind the associated errors or warnings.
We have more than 10k merchants using our plugin, and we are committed to addressing any concerns they encounter so if our plugin raised similar errors or warnings, our other merchants would have already expressed the same concern through the support forums.
Your feedback is invaluable to us, and we are dedicated to addressing any further issues you may encounter.
Please don’t hesitate to reach out to us for ongoing support and assistance.
Best Regards,
Team Simprosys!
