If I click on any 'news' link, such as that for the Bug Sur 11.3 release, I get an error of this form :
Sorry, there is a problem
Something went wrong. Please try again.
Error code: EX0
It happens across multiple machines, using Edge (the Chromium fork), unless I'm in private mode. I wondered what the error code implied, to see if I can find out what's interfering in the regular mode.
