Hello socialbear,
Thank you for your reply.
I have reviewed the logs, it appears there is a 401 HTTP response error.
This typically indicates a problem with the authentication credentials. To address this, it would be important to check if the Google Account used has the required permissions to link with the Google Merchant Center.
Please verify the account permissions and ensure that the correct Google Account is connected with the necessary access rights. Additionally, please check if any restrictions on the Google Account might be preventing a successful connection.
I will also recommend disconnecting the Google account and connecting it again. This might fix the connection issue between Google Listings & Ads and Google Merchant Center
Once you have tried these steps, if the issue persists, please get back to us with this information, and we will continue to work with you to resolve the issue.
I appreciate your patience and cooperation as we work through this together. ??
Best regards.
