If you have the Yahoo notification option activated, you can get weather, stock, sports, business, national, and international news updates on your phone right away. However, if you face Yahoo notifications not working, you haven't enabled Yahoo mail notifications. To begin, go to 'Settings' on your device and select 'Notifications.' Then select the Yahoo Mail app and hit the toggle button to accept notifications. Toggle the toggles to activate various notification types. In your Yahoo Mail app, you may also enable alerts. To do so, go to the profile section of your Yahoo mail app and pick notifications. Then, click on 'Allow notifications for all messages and features' or 'Just the categories I choose' from the drop-down box. Select the toggle to enable the sorts of alerts you wish to receive.
