My KakaoTalk app is loading slowly.

Your app may take a longer time to launch if you have too many chatrooms or unread messages. We suggest you read all unread messages and leave chatrooms once you finish chatting with your friends. To leave a chatroom, tap the "Edit" button on the top-left corner of the Chats tab. Then tap the "-" button on the left of the chatroom you want to leave and the "Leave" button will appear.

You can also swipe a chatroom to left from the Chats tab and tap the "Leave" button.   

Please note that if you leave a chatroom, the chatroom and its chat history will be permanently deleted.
