A. 1. Check the app's FAQ or help section: Many apps have built-in help sections that can provide answers to common issues without needing to contact customer service. 2. Look for community forums: Search online for user forums or communities where other users may have shared solutions to similar issues.

B. 3. Document your issues: Keep a record of the problems you encounter. If you do receive a response later, having detailed notes can help you explain your situation more clearly.
