Gmail Keeps asking for Aplle ID and PW
Added a gmail account last week. All worked fine until I changed my email address/I'd. Now every time I want to read mail or reply it asked for my ID and PW! Not fun. And I noticed when I go into my iCloud pref. my new email address is there of contact info but at the place where my picture. And name is it still shows my old email address. Can't figure out how to fix. Any ideas? It's iPad Air with 8.1.3
iPad Air Wi-Fi, iOS 8.1.3
