As per the App to work properly , the Cash On delivery (COD) from the Manual settings need to be disabled and a new Cash on Delivery (COD) from Alternate Payments. We were able to disable the COD from manual payments. However , there is no COD in Alternate Payments for us to enable the new one. So customer still see COD as an option in the next page , even after they select Prepaid

The app says it has better flow and we should deactivate Manual COD option and activate COD in alternative payment option. But there is no option in alternate payment methods for COD! We are still waiting for selective product selection for COD as well. The video link which is being shared in many other reviews is also not working!

I've been using this app since 2016 with no issues but recently I deactivated it for a week because I was accepting only prepaid payments for that period. Now I want to reactivate it again so I went to the app but there's no "Reactivate' button (there was a 'Deactivate' button when I deactivated it a week ago) and there's a highlighted message, "Cash on Delivery has not been activated. You should activate the new Cash on Delivery payment method to make it available to your customers on checkout. You can reactivate it by choosing 'Cash on Delivery' from your 'Alternative payments' settings.'" So I went to 'Alternative payments' settings but there's no 'Cash on Delivery' option. At this point, I contacted support (this app is Shopify-owned) and they emailed back with step by step instructions to activate 'Cash on Delivery' in manual payment settings. I explained with screenshots that I want to activate 'Advanced Cash on Delivery for India' app and not the 'Cash on Delivery' in manual payment settings as those are two different things—the former comes with features like Cash on Delivery availability checker, Order subtotal limit and Postal codes which the latter does not have.
Support replied back, "Those steps I provided you will allow this to be activated, even though in the Payment providers settings there isn't the option for the specific app, activating the payment option using "Cash on delivery (COD)" will allow the app to work on your store."
Even though I clearly remember this wasn't so when I first got the app back in 2016, I followed her instructions thinking maybe they changed the activation process. After I activated 'Cash on Delivery' in manual payment settings, I went to 'Advanced Cash on Delivery for India' app and there's a highlighted message, "Deactivate existing ‘Cash on Delivery (COD)’. You should deactivate the existing ‘Cash on Delivery (COD)’ manual payment method which is currently enabled in your payment settings." Below it, another highlighted message, "Cash on Delivery has not been activated. You should activate the new Cash on Delivery payment method to make it available to your customers on checkout. You can reactivate it by choosing 'Cash on Delivery' from your 'Alternative payments' settings."
It's really frustrating because I need this app to be up and working like before but support is unhelpful and has no idea how this app even works. Shopify is unnecessarily overcomplicating such a simple thing. Please fix it.
