Order Receipt is not generated after Purchase

Hello team,

I am using both stripe payments and invoice payments based on cart conditions. When I select Stripe payments, the order is processed successfully and an order receipt is generated. But when I am purchasing via Invoice payments, the page redirects to the cart which says “empty basket”. But the buyer receives the mail and I can see the orders in the backend. Only the receipt page is not generated after purchase.

If you want to test, you can?go to this page?and create a group with more than 1 seats. Then you can checkout with invoice payment.

Please help.
