clearing cookies works once... then I can get to the Help documents.
I log out and start Help from a bookmark ...
https://pro.arcgis.com/en/pro-app/latest/help/main/welcome-to-the-arcgis-pro-app-help.htm
and it redirects me somewhere trying to log me in or out depending on its mood and I have to shut it down.
As for .... and local storage on the Pro site .... I don't store anything other than on my local machine. Are you referring to something in my c:\Users folder??
I also have a real active Licence.log file in my C:\Users\... me ... \AppData\Local\ESRI_Licensing\Logs
folder.
No clue why it is checking for my license multiple times, especially since I only opened Pro up twice today.
... sort of retired...
