Getting APP_NOT_INSTALLED error even though the PhonePe app is installed on the device.

[KumarSantanu]

I cloned the official PhonePe PG Android Demo from the official GitHub repository. I entered my production MID and key, but I am still getting the APP_NOT_INSTALLED error. This happens regardless of whether I use PhonePeEnvironment.RELEASE or PhonePeEnvironment.SANDBOX

Logs:

Steps to Reproduce:

1. Clone the official [PhonePe PG Android Demo repo](https://github.com/PhonePe/phonepe-pg-android-demo.git).
   

2. Enter production MID and key in the demo app.
   

3. Call the PhonePe payment API using PhonePeEnvironment.RELEASE and PhonePeEnvironment.SANDBOX.
   

4. Observe the APP_NOT_INSTALLED error.
   

Expected Behavior:

The transaction should proceed without the APP_NOT_INSTALLED error, as the PhonePe app is installed on the device.

Environment:

• PhonePe SDK version: 5.0.1
  

• PhonePe app version: 25.01.10.0
  

• Device: Oneplus Nord CE2(Tested on physical device)
  

• PhonePe Environment: PhonePeEnvironment.RELEASE and PhonePeEnvironment.SANDBOX
  

I have tested the app on multiple devices and ensured the PhonePe app is installed. I also tried both the sandbox and production environments, but the issue persists.
