Hello Ken! Thank you for your question. I will be assisting you today.I'm sorry about the issue. Do you use the Mail app? Or do you use the Gmail app? Or do you go to the gmail.com website to use email?Let's try a basic step first: Please press and hold both the Power button and the Home buttons together on the iPad for at least 10 seconds, until the Apple logo appears, then wait a bit, then check.
Please click on the Reply to Expert tab below, and reply back to me, so I can help further if there is still any issue. Thank you very much
Sorry, are you able to sign in / use your gmail at the website http://gmail.com/?
Let's use the official Gmail app. Please go to the App Store, then search for Gmail, then download and use it.
Please let me know if there is still any issue. Thank you,
