Experienced Mobile Developer Needed to Fix Stripe Subscription Error in Existing App

We are seeking a skilled mobile application developer to diagnose and resolve a critical issue with the subscription feature in our existing mobile app. The application is currently in development, and users are unable to complete subscription payments due to an error that we suspect is related to our Stripe account connection or its integration within the app.

The primary goal of this project is to identify the root cause of the payment malfunction and implement a robust solution. The selected freelancer will be responsible for a comprehensive review of the relevant code, the Stripe API configuration, and the overall payment flow.

Key Responsibilities:
1.  Thoroughly review the existing mobile app's codebase, focusing on the subscription and payment processing modules.
2.  Investigate the functionality of the subscription feature to pinpoint where the process is failing.
3.  Examine the Stripe account settings and API configurations to ensure correct setup and connectivity.
4.  Implement the necessary fixes to resolve the Stripe connection or payment processing error.
5.  Conduct extensive testing of the subscription purchase flow, payment status updates, and user access validation post-payment to ensure full functionality.
6.  Verify that the entire application operates correctly and stably after the fixes are applied.
7.  Provide a clear explanation of the identified problem, the steps taken to resolve it, and any recommendations for future maintenance.

We require a developer with proven experience in mobile app development, particularly with payment gateway integrations like Stripe, and a strong understanding of debugging and quality assurance processes.
