WooCommerce Error in Version 9.6.1 or 9.6.2

Hello danzilana,

Thank you for contacting WooCommerce support.

I understand that after updating to version 9.6.1 or 9.6.2, your product page width is reduced, and the ‘Add to Cart’ button is not working.

Your site’s appearance is controlled by your active theme, so I recommend reaching out to your theme support for assistance.

Let me know what they say, and I’ll be here to help if needed. ??

Best regards.
