Can sign in but no launch, help!

I am using Chrome browser on a Windows 10 machine. I have had no problems before. Now when I go to plex.tv and click sign in, I can enter the correct username and address, but it just flashes and takes me back to the front page saying sign in or sign up. I click on sign in again, and everything is green saying username and pass correct, but again takes me back to front page with no launch button. Help please!

Clear the browser’s cache and try again.

Edit - Also clear any cookies related to Plex.

Did that, hasn’t fixed the issue. The text I get says “You have successfully signed in, please wait while we redirect you…” then it takes me back to the home screen.
