Can’t get yahoo mail on IPad Pro or my iPhone 12 Pro Max?

I am still not able to get my Yahoo mail on either my IPAd pro, or my iPhone 12 Pro Max. The message says it’s unable to connect to the server. The last date of mail on my iPad is July 1, 2021. I deleted yahoo mail on my phone and then re loaded it. None of my yahoo mail returned. Help! What is going on. It’s so inconvenient to go to google to get my yahoo mail. I am able to get gmail on my phone and iPad. Is there a battle between Apple and Yahoo?
