teamview login website

Every time i login to my computer a website "How to use TeamViewer" opens in Edge.  Ive used teamviewer for years to help my parents with their computers so when i got a new computer one fo the first things i installed was teamviewer.  Now though, it is extremly annoying to have this popup each and everytime i log in.  I have looked in Windows Startup, Edge Settings, IE Settings, Teamviewer settings, I cannot find how this is opening and how to turn it off.
