I've been reading news by clicking links in news digest emails for years. Starting yesterday, most (like 80-90%) of the links to the articles send me to a page that says "we couldn't find that page so we brought you to Yahoo.com". Strangely, a link here and there will work and actually take me to the article.
I'm using Windows 11 and Firefox. I tried clearing cache and cookies, and that made no difference.
