A. 1. Use search bar: Instead of relying solely on filters, use the search bar to find specific items or categories. 2. Sort items: After performing a search, use the sorting options available (like price, popularity, etc.) to narrow down your results. 3. Provide feedback: While not contacting developers, consider using the app's feedback feature to suggest more filtering options for future updates.

B. 4. Check for updates: Ensure the app is updated, as new features may be added in future versions.
