Shopify to Google Merchant Feed Setup

Hello, we already have a running Shopify store in Italy with a running merchant center. We are now entering the german market, so we created a new feed and and a new merchant center. I need someone with google merchant experience to deal, as we don t have time to, with all the issues and complete BY THE END OF THE CURRENT WEEK the settings and make sure all products are going to be approved.

For feeds we use MULTIFEEDS app on Shopify

Key Requirements:
- Correct a Google Merchant Center feed from our Shopify store
- Troubleshoot any issues that may arise during the process
- Ensure all products are successfully uploaded and visible on Google Shopping with any error
