Why does my Yahoo Mail won't open

First,ensure that your internet is providing stable signal strength. Clear the caches
of your browser and update the browser to log in to your Yahoo account. Ensure
that you have installed the latest version of Yahoo Mail and the OS. Restart
your computer and retry to load the emails. Sometimes, force stopping and
rebooting the app can also resolve the Yahoo won't load issue as it refreshes the active memory of the app.
