How to fix Can’t Add Shipping Details In Google Merchant Center?

The issue is that as of two weeks ago, users can no longer add manual shipping rates using the Google and Youtube app in Shopify. In the Google Merchant Center, users receive a message indicating that Shopify handles Shipping (Delivery) settings, but there is no option available to add their shipping rates.

There are two potential solutions to fix this issue:

• Option 1 (untested): Disconnect Shopify in the apps and services area of Google Merchant Center, check if the option to add shipping details appears, wait a few hours if necessary, and then reconnect the app, likely through the Shopify app.

• Option 2: Revert to Google Merchant Center classic by clicking on the question mark in the top right corner and selecting 'Use classic Merchant Center'.

To revert to Google Merchant Center classic, follow these steps:

1. Click on the question mark in the top right corner of Google Merchant Center.
2. Choose 'Use classic Merchant Center' from the options presented.
