This app has recently developed major bugs. The conversation bubbles constantly disappear, it frequently closes while I am in the middle of typing a message, the keybord will open only when it wants to then there is a delay between when I type and when it appears on the screen, and there is often a long delay sending messages. An update is available and I have tried to install it a few times but it stops downloading at 44% everytime. Please fix. It is causing me to want to throw my phone.
