Billing Pages Not working on App or Webpage

@XfinityAlyssaA

When I click on "bill due date" on my account, I get this screen. On the app it's the same.

Thank you for providing that photo @user_7vwp2j so we can see what you are seeing. To be eligible to move your bill’s due date, you must have completed at least one billing cycle, and your bill must not be past due. Once you change your bill’s due date, you need to keep that billing date for at least 6-months. To confirm, do you have any past due balance on your account or have you changed your billing due date in the last 6-months?
