I can no longer sign into my yahoo mail account because i am working from a Macair 10.15.laptop using Catalina. I have been using Safari as a browser, and am no longer able to update the app on my laptop. I have had no luck trying other browsers. I can only maintain my classic yahoo mail account if I am unable to access my email. Any suggestions? I don't want to switch to another email, but I need one that works!
