All of the sudden my yahoo mail hasn't been working on my phone. I stopped receiving emails and now anytime I try to manually refresh it has an alert - login failed. I tried deleting the account and going in and re adding it but it says my username and password don't match up. I know they are correct and like I said it had been working fine for the last 6 months and then just a couple days ago started having this problem.....any help would be greatly appreciated!!
