Hi @payal1995!
Thanks for reaching out to us with your question. If you’ve successfully completed the setup process to connect your store with your Facebook Business Manager account, then that’s a great first step! It should have let you choose the pixel you’ll want to use for your site during that process.
If you have already done that, and would like to change the pixel in use afterward, the easiest method would be to use the Uninstall button on the plugin settings page at WooCommerce > Facebook. This will refresh the page, showing the Get Started button again, and then allow you to run through the connection process again.
During the Confirm Settings page, you can then click the pixel option and choose the correct one you’d like to connect with your store: https://cloud.skyver.ge/z8uZyJLW
Could you give that a go and let me know if you counter any issues? ??
Cheers!
Simon.
