I'm unable to add yahoo mail after changing my password.

[AC Question]

I changed my yahoo password and have since been unable to access my yahoo mail account. I downloaded the yahoo app but removed it. I want the yahoo account to be added with my other email accounts. Using settings and then add account, I get a message saying "login information incorrect. Try again." I changed my password a second time but I get the same message. I do not know how to set it up using the manual setup option. I'm using an LG phone.
