Some common pain points developers might encounter while building an app include:

1. Versioning: Managing different versions of APIs and SDKs can be challenging. Square provides version-naming schemes to help developers understand and manage different versions.

2. Authentication and Authorization: Managing access tokens and other credentials for identifying or authenticating an application and authorizing access to resources in a Square account can be complex.

3. Frontend and Backend Development: Understanding how Square APIs and SDKs are used in frontend and backend development can be a learning curve for some developers.

4. Data Management: Collecting and managing customer information responsibly, accommodating language preferences, and understanding supported data types across Square APIs can be challenging.

5. API Lifecycle: Understanding the lifecycle of Square APIs, including beta, general availability, deprecated, and retired stages, is crucial for maintaining the app.

6. International Development: Developing applications for sellers located in other countries can present challenges due to differences in regulations, languages, and cultural norms.

7. Security: Ensuring the security of customer data, especially when dealing with payments, is a significant concern. Square provides guidance on best practices for collecting information, but implementing these can be a challenge.

8. Integration with Other Systems: Integrating Square’s APIs with other systems or APIs can be complex and may require a good understanding of both systems.

9. Testing: Ensuring that the application works as expected under different scenarios can be time-consuming and complex.

10. Performance: Ensuring that the application performs well under load, especially for applications with a large number of users or high transaction volumes, can be challenging.

11. Compliance: Meeting regulatory and compliance requirements, especially in the financial sector, can be a significant challenge.

Remember, these challenges can vary based on the specific requirements of your application and the skills and experience of your development team.
