I recently received an email about an app not downloaded by me. So I changed my password immediately. (I don't know if matters, but I had to do this from my office.) Now I'm getting a message on my iPhone that says "Verification Failed. The certificate for this server is invalid. You might be connecting to a server that is pretending to be "setup.icloud.com" which could put your confidential information at risk."
So I went into my account and tried to use my new password but I still get that message. Please advise.
