I keep trying to sign in to my existing account as prompted in an email. It says to sign up, when I click, change to sign IN, enter my email address, click continue, it just flashes and goes nowhere. When I go back to email the message is still there. Even now I am logged in but still prompts me to sign up.

Works When It Wants.

The app is very temperamental and unreliable. I thoroughly enjoy it when it's does work and not repeatedly requesting me to sign in, yet still doesn't activate when I click to sign-on and then click "Continue to Grammerly." It worked for a while when I re-installed TWICE. I read the troubleshooting instructions, but now the sign-in prompt is not showing up in order for me to follow the troubleshooting prompts. UGH!!

Turns off by itself many times.

awesome
