Continue button greyed out

Hello Jislaaik,

Thank you for contacting WooCommerce support.

I understand that the Continue button stays greyed out after adding your Google account and address in Google for WooCommerce.

This usually happens when a required pre-launch item is incomplete, often the store address.
Please go to WooCommerce > Settings in WP Admin and make sure the address, city, postcode, and country are filled in.

Let me know how it goes.

Best regards.
