I'm sorry about the issue. I'm another tech. I will try to help you with this.
- On the iPad, please press and hold both the Power (On / Off) button and the Home button (which is located right below the screen) together for at least 10 seconds, until the Apple logo appears, then wait a bit, then check.
- Are you currently able to sign in your Comcast email address with your Comcast email password ***** the Comcast website below (on the computer and/or iPad and/or iPhone):
Note: Password ***** *****
- If yes, on the iPad, can you please go to App Store, then type/search for xfinity connect then install the XFINITY Connect app and use it for your comcast email.
- If no, it looks like you got the wrong password. Or once in awhile for security purpose, Comcast wants you to change your comcast account password ***** the comcast.net website for some devices. If needed, I can connect remotely to your computer and check / confirm your comcast email password ***** through your computer together with you.
Please reply at the box below to continue troubleshooting. Thank you for your patience.
