Hi @Gunasekar ,
Have you reached out to Google directly about this? I’m thinking they might be best to look into why this might be as Shopify wouldn’t have much to do with what the Google Merchant center approves or disapproves. You can see their help center support page here and the contact is at the bottom highlighted in the screenshot below:
Let me know if there is something more Shopify specific and I can take a closer look into it for you.
Thanks, Nick
