Old iPad--software is 12.5.7. I deleted the Yahoo mail app and am trying to reinstall this app. Endless loop--id, password, yahoo, id, password, yahoo, etc. How can I reinstall this app please?

Hi corvet11,

welcome to the Apple (user-to-user) Community.

Seems the latest Yahoo Mail app in the App Store may not be compatible with your older operating system, if that is the app you've been trying to install:

Apple's article for iPadOS 12:

How to: Get apps and games in the App Store on iPad – Apple Support

An alternative:

Wondering if you may be able to just add your Yahoo eMail account to the Mail app on your iPad instead, in order to restore access your Yahoo eMail.

Eg: For iOS 12: In Change the iPad settings – Apple Support

You can: scroll to: Set up mail, contacts, and calendar accounts

Eg: says (On iPad):

Go to Settings > Passwords & Accounts > Add Account.

To add a mail account, tap an email service—for example, Google, Yahoo, or Aol.com—then enter your email account information.

NB: If you are missing any information that needs to be entered:

You could likely log-in to your eMail account on the Yahoo website, and retrieve whatever you need. (Eg: If you forgot the password, you can usually get a new one from the log-in webpage.)

All the best :-)

Thanks Kuw12. I don’t use 2 factor authorization.

I guess Apple no longer supports this iPad and would like me to just buy a newer one.

Happened to me over and over. I disabled 2 factor authentication and it worked
