Shopify - No return call back to order confirmation after succesful checkout

i have a shopify store set up for online ticket sales. https://m113qh-wk.myshopify.com.
Here’s what’s been done so far.

  1. the installation of the app via a link shared by paynow.

  2. A challenge was faced at the checkout page during test integration as the Faked success tab was not triggered - Tino resolved this.

  3. Tino manually set the Paynow gateway as live yesterday, as per our request. I can confirm that it is now live, as we tested this yesterday

Now that you are caught up, here is the current issue below.

Upon a successful transaction ( ecocash) I get a notification of a completed payment, this is good but after the payment, paynow redirects the page back to the checkout page and not the order confirmation page.

This is a problem because the customer also does not get an automated email to receive their ticket order.

I suspect that it might be that Shopify does not recognize the successful payment since when I use the native payment gateways within paynow ( visa) the automated response is triggered. See a photo of the desired outcome.Desired%20outcome

Use of Visa cards is now desirable for this project, we would like to make this work with ecocash and inn bucks

Good day, may you kindly inbox your Integration ID so that we can check the transaction?
