App Debugging Assistance

I'm in the development/testing phase of my app and encountering some issues that I need help with. The app is built using cursor.ai.

I need someone to guide me through fixing errors and understanding what I might be doing wrong. The issues I'm facing include:
- Functionality errors
- Integration problems

Ideal candidate should have experience with:
- Debugging
- Application testing
- Cursor.ai platform

Please note, this is not just about fixing the bugs but also helping me understand the development process better.
