Recently it has been nerve-wracking trying to chat on the app because it was so buggy. It used to work properly until the last update when messages wouldn't send, and if you closed the app they disappeared, and notifications of recieved messages did not arrive. Stickers take forever to load, and if you try sending one it bugs the app, making messages unable to be send nor recieve ones in return. Overall an awful experience and I hope it's fixed.
