Acquia Commerce Manager has the following known issues:
You cannot have a cart block and a cart form block on the same webpage, as this prevents the cart form block from updating.
Initial configuration may require you to review the checkout flow settings and then save the form to ensure the checkout flow IDs set properly.
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.
If the Commerce Connector Service cannot be contacted during the checkout process, the checkout process will fail.
If you encounter any difficulties with your Acquia Commerce Manager subscription, contact Acquia support for help.
