If there are multiple payment methods available and someone has used a different payment method, it depends on how the system is set up. The restriction you mentioned might prevent someone who used another payment method from continuing if the restriction is specifically designed to limit access only to those who used a particular payment method.
For example, in the case of manual enrollment to the complete course, if the restriction is set up to grant access only to those who paid through a specific method (let's say online payment), then someone who used a different method (like bank transfer) might be prevented from continuing unless they fulfill the requirement of the specified payment method.
