Could use some enhancements – WhatsApp Messenger Review

It's an essential app now. I am facing an issue that the search bar doesn’t load immediately when opening the app on iPhone, there’s a delay. When I click on a conversation immediately when I open the app, I find that I clicked on the wrong thing because that bar just loaded. I also wish they add more ways to classify chats according to different categories or importance.
