A. 1. Check permissions: Ensure that the app has the necessary permissions to access your contacts or share content. Go to Settings > Apps > Cram.com Flashcards > Permissions. 2. Use alternative sharing methods: If the in-app sharing is not working, consider copying the link to the flashcard set and sharing it through your preferred messaging app.

B. 3. Restart the app: Sometimes, simply restarting the app can resolve temporary sharing issues.
