Hi @0sukaru,
Google Listings & Ads plugin uses the Content API method to sync products with the Merchant Center. The products are submitted as batches to Google and are assigned a unique REST ID based on their properties. This ID is stored locally to identify each product when interacting with the Content API. This means there shouldn’t be any feed format that Google will mark as wrong.
However, can you provide screenshots showing the issue for better assistance on your end? For screenshots, you may use https://snipboard.io. Please follow the instructions on that page and then paste the URL into this thread.
Additionally, please can you share a copy of the following:
- System Status Report: Navigate to WooCommerce → Status. Select Get System Report and then Download for Support.
- Fatal Error log: Share a copy of any fatal error log found under WooCommerce → Status → Logs.
You could copy and paste your reply or share it via Mozilla Community Pastebin and share the link here.
Looking forward to helping you.
