Acquia Commerce Manager has the following known issues:
Cart blocks and cart form blocks can not be on the same page
You cannot have a cart block and a cart form block on the same webpage, as this prevents the cart form block from updating.
Review checkout settings during configuration
Initial configuration may require you to review the checkout flow settings and then save the form to ensure the checkout flow IDs set properly.
Drupal provisions user accounts during checkout
During the checkout process, Drupal provisions a user account for the customer. The user is not informed the user that they have created an account. Returning customers are expected to sign in, as email addresses must be unique.
Connector service failures cause checkout failures
If the Commerce Connector Service cannot be contacted during the checkout process, the checkout process will fail.
