New user can't log on

Hi
I’ve been using Sketchup free for a decade and I’m a total amateur. I just bought Pro because I know the product and I want to play with new extension ideas on my house. The app on my laptop asks me to login, I am logged in online, the app is still asking me to login. What am I doing wrong?
help appreciated… Andrew

Being logged into a SketchUp web page in a browser does not let the desktop application know that you are signed in. Look at the Help menu in SketchUp to see if you can sign in from there.

If you seem to be signed in on the Help menu, go through this article in case it applies to you:
