Pay order button not visible in orders listing?

Hello,
I have just updated to 3.5.0 and then 3.5.1 and was testing the various new features

about this one for 3.5.0
We've added a "pay now" button on the order details page.

I cannot see any "pay now" button in my orders page in frontend
see: www.screencast.com/t/caqwu2z6V0Q

I tested ordering with an offline payment method though, not sure if this is why
I also do not have any template override for the orders listing,pay and show templates

Also about this new feature for 3.5.0
The payment notification email now uses the email system of HikaShop and has its own editable email instead of a text version through Joomla email system. That way, it can contain all the order information instead of just the notification message.
could you elaborate because I dont' understand what this is affecting, as far as I see the system > emails are still the same, what are you referring to exactly?

Thank you

I had not checked "unpaid" for the "created" status in the order statuses page
