There is no “push” option on the iPhone mail app for Yahoo only “fetch”. I am missing important emails because the emails only load when I open the app. I use the yahoo app for news, etc, but I prefer the iPhone native app format for mail. You are trying to force me to use your app and this is not right. Poor customer service. I am on several waiting lists to receive the Covid vaccine. I have now missed 2 emails for opportunities to register to get the shot because, by the time I opened and saw the email (which was only 7 minutes after I received it), all the registration slots were filled. I don’t have time to sit all day and manually open my email every minute. So, thanks to you, my email account is not so “e”mail but more like snail mail. I’m very careful with safety precautions so If I get Covid because I missed chances for the vaccine, I’m not going to be happy with you. Seriously...please fix this.
