This started a little while back after iOS 10. My yahoo email randomly crashes I.e. There are ZERO emails shown in the mail app. It takes some time for the mail to load back. I can log into the mail from website and everything is there. I have changed password, deleted the account from iPhone, ended all sessions via yahoo mail website and started new sessions. I don't use any apps to check the mail. This is the only email that's doing this. Any one else having this issue? If so, any fixes or is this something that we will have to live with?
