Hi Sagar,

Amazing Blog I must say. I'm trying to set up RazorPay for the first time. I used a different method, creating a JSONObject and passing it as checkout.open(activity, orderReqObj). However, I'm having trouble with the UPI payment option. Even though I have three UPI payment apps installed on my device, the UPI payment option is not visible. I suspect there might be an issue with the generated key, as the UPI apps are visible when I use my friend's testing key. Can you provide some guidance or assistance on this issue? I would appreciate any help.
