Crazy slow

Not understanding how there are so many good reviews. This app is very slow and I cant make sense of why messages do not appear to be stored locally. I need to wait almost 10 seconds for a message thread to load as it acts like it needs to be fetched before it can be viewed. Long way to go compared to companies like whatsapp and messenger.
