Running Catalina on my early 2015 MacBook Air, and using MSN for my "main page"on Safari. The particular problem has happened in the past, went away, and has now reappeared big-time. Basically, when I log in MSN news comes up, but when I click on a particular article it will start to load, stop, and then sit there until I back up. Almost every, if not every article that comes up on the MSN page. Websites will load, but not articles. HOWEVER, if I go to File and select New Private Window, MSN articles will load! HOWEVER, if I got to File and then New Window, the articles will not load! Initially thought my problem might be the apartment building's wifi, but would think the fact that a New Private Window works would mean the wifi is working. When this happened before, I switched from MSN to Yahoo for awhile, then went back to MSN later and MSN had started working. For those of you who say call Microsoft, I have and they stop listening as soon as Mac and Safari are mentioned. Does anyone have an idea?
