eCommerce Cerber Blocking Sales

I am new to Cerber. I have added it to an eCommerce site and it seems so strong that it stops people from purchasing on the website. I have searched for a video to show how to set Cerber up but only found one. Is there any training available, please?

We’ve developed WP Cerber with WooCommerce compatibility in mind. However, we expect WP Cerber to work normally alongside most properly developed WordPress plugins. Which eCommerce plugin you are using on your website?
