🌸 Happy Teacher’s Day! 🌸

Teachers are not just the ones in classrooms…
👉 A book can be your teacher.
👉 A mistake can be your teacher.
👉 Even life itself is the greatest teacher of all.

On this special day, let’s celebrate every person, every moment, and every experience that helps us grow. 🌱

✨ Remember: Learning never ends, and growth never stops. Keep believing, keep working hard, and keep moving forward. 🚀

With gratitude and positivity,

Initially, everything works fine. But suddenly, your app becomes slow when fetching contacts using get(contactId).

What could be a possible reason for the slowdown?
