When doing final live testing of PayPal purchase, I set a product for $1 subscription and $1 signup fee.

After payment is accepted from PayPal, it sends you to:
https://www.heavenlynotes.cloud/checkout/confirmPayment?orderpayment_type=payment_paypal&paction=display&token=EC-5TJ39997CT7216218&PayerID=YCL8LJ53U3U32

Then I click the "View My Account" button and it takes you to the 404 page below:
https://www.heavenlynotes.cloud/component/j2store/confirmPayment?orderpayment_type=payment_paypal&paction=display&token=EC-5TJ39997CT7216218&PayerID=YCL8LJ53U3U32&Itemid=863

I tried all three Callback URL PayPal choices with mostly the same link.
Order is showing up in my account but the subscription is not.

I looked in the subscription product app and couldn't find any settings in there to help.

Also I set up "Add to User Groups" corresponding the product and only access level given is "Registered".

I tried to get Joe to look at it but he is out of town.

Any help will be appreciated!

I am seeing the attached "Quick Start Checklist" with order confirmation Menu in red but it does not allow me to click it for additional information on how to fix the issue. There is a menu item named "Order Confirmation" but I can't find where to link it in the J2Commerce component. 

Hi Adam,

It is created in the J2Commerce menu. I attached it for review.

It was already set up over a month ago. Somehow the component is not recognizing it. I don't see any blocks in Akeeba admin or Cloudflare.  

Done, thank you!
