I've suddenly stopped receiving email from my BT (Yahoo) account on my iPhone. Eventually decided to delete and re-install the account, but the Yahoo set-up just gives me a 'Oops, something went wrong' message. I can set-up as an 'other' account, but do not have the option of importing contacts - so I've effectively lost all my contact information!
I haven't knowingly done anything else. Is this issue isolated to me, or is there a bigger known issue at the moment?
