I'm presented with this prompt immediately after already entering my email address and password. "It" won't accept addresses ending with: comcast.net (such as mine), nor xfinity.com
So what's the objective? I don't have any other email addresses. Thanks
No one can see the image you posted yet becausxe it has to be approved by the forum administrator. That might take a day or two. But I assume you are referring to the setup instruction for when you first created your user ID for the account? If that is the case, it's a security thing. The alternate email address would be used for account recovery in the event your account got compromised by a hacker. It has to be an email address you have from some other email provider like Yahoo, Gmail, Outlook.com or some other. A lot of other providers do the same thing.
Thanks for the response. I've been an Xfinity email user for multi-years. This prompt initially appeared within the past month. My work-around: EXIT from the prompt, re-enter user id / password, and I'm there. There is no option on the prompt such as: "I don't have another address" or "skip".
