I have a new laptop to which I downloaded SharePoint Designer 2013. I am getting a 403 forbidden when trying to open a site from the new computer but when trying to access the sites from my old computer with an SharePoint Designer 2013, I am granted access. In the new download on the new computer, my account is set to the same account as the old instance. I am a global admin. Our sites are classic sites right now until we develop in modern team sites and communications sites, so that is not the issue. Any help will be greatly appreciated.
