Thanks for your help. I added the account (which wasn't there, but is now). But I'm still not able to access my yahoo email messages.
Perhaps I should have mentioned that I have two email accounts on my iPhone. One for work, which I can access by clicking on Mail; and my personal email -- my yahoo email account, which I used to be able to access by clicking my yahoo mail app icon (m.mg.mail.yahoo.com/... ) or by navigating to the Yahoo site (www.yahoo.com and clicking the Mail hyperlink).
Any other ideas? I still just get a blank white screen with dots blinking in the shape of a square.
Yes, I'm using Safari. The Mail icon (at the bottom of the home screen) is taking me directly to my work email, as it should. But the Yahoo Mail app is giving me the blank white screen with the dots blinking in the shape of a square. The same white screen appears when I try to access my yahoo email through the yahoo website using Safari.
Before I hit "reset network settings" I'd like to clarify two things.
1. I'd like to continue getting my work email from the Mail icon on my homescreen. (This is currently working.)
2. I'd like to get my yahoo email on the yahoo app and through the yahoo website via Safari. (This is currently not working.)
Will "reset network settings" allow me to do the above?
Thanks for being so patient.
