I"m getting: “There was an issue processing your payment. Try again or use a different payment method.” when testing the Shopify app. I followed the instructions here: Paynow ZW - Accept Mobile Money, Debit & Credit Cards | Shopify App Store and double checked the Integration ID and Key and nothing is working.
I also tried to request for live and no email feedback came.
The Shopify App Form is also confusing, it has both test and live credentials required, so I just ended up entering the same test credentials for both.
Please assist.
