Emojis

Hi, there was a change a while back, and now it's hard to add emojis in chats. They disappear and reappear—it's not easy to add them. I don't know if this is just happening to me, but it's really weird. It's hard to add them. They used to be on the right side, like in WhatsApp, but when they moved them to the left, this problem started. Thanks!
