Suddenly can’t send message

Out of the blue the return key on my iPad adds a new line instead of sending my message. It’s always been slow and buggy. I don’t understand why this app is so bad.

Not so great

App is very slow to open. Keyboard doesn’t always pop up when text field is tapped.

Horrible app

Super buggy to the point where it’s essentially unusable due to sheer frustration.
