While in the Classic Experience in SharePoint 2019, when trying to get to the 'Help' option (click on "?" and then "help"), a pop up window comes up with "Sorry, you don't have access." instead of a help page.
In the Modern Experience in SharePoint 2019, there is no issue, it goes to the help page.
Developers are still using the Classic Experience for customization and so users cannot access the help page.
