Problem Description

We need help fixing the last bugs to make a web mobile app functional, which include:

• In the deployed version, users are randomly logged out sometimes
• Issues with displaying correct audio player after generation
• Mobile navigation menu persistence
• Desktop responsiveness (the app is mobile first)
• Proper debugging of all key features on multiple devices (20-point checkist)

Acceptance Criteria

Key criterias:

• We will ONLY work with individual freelancers, no agencies. If you are subcontracting the work to someone else, do NOT apply
• We will ONLY work with individual freelancers with real Replit experience. If you want to download the project and fix it locally, do NOT apply. All changes have to be made inside Replit
• We're looking for smart, detail-oriented developers. If you're a developer who will skip details and who is not good at finding scalable solutions, do NOT apply
• We need a developer who can properly follow a 20-point debugging checklist on our app on multiple devices for the deployed version and fix all issues
