I added exceptions for tracking for cgcookie.com and cloudflare.com. You can do so multiple ways but padlock on the left of the address bar has “Tracking Prevention” dropdown menu choices “Block (default)” or “Off”. My guess would be the default used to be “Off (default)” (but I don’t know because it just worked before, and I didn’t check it).
It must have been caused by a recent security update of Edge or Windows 11 by Microsoft that was done a few days ago.
By the way, don’t forget about the Edge Developer Pane/(Console and Network). It is what showed me cloudfare.com was having trouble.
