Why is ChatGPT not opening when I launch AI Writer?

Are you able to see the AI writer to the left but ChatGPT is not appearing to the right? You probably have a popup blocker enabled because every browser has them. It's very easy to disable this though. You should see up here at the right if you're in Chrome, a popup blocker icon. Just click that and choose "Allow all", and in the future, it will always allow both of the popups that are required to use the AI writer. If you don't see it here, it could be over here on the left side of the browser bar.
