UPDATE - 2016.04.26

Now with iOS 9.3.1, go to Settings, Mail, add mail account.  The "Google" choice works again!!  Much simpler than "other" as below ; )



[ keep the following for awhile; everyone should be updated by next school year ]


Click on the Mail icon (usually at the bottom of the Home screen, unless you moved it)

Instead of adding your account using "Google", choose "Other"


Then add the email account using imap.gmail.com (for incoming) and smtp.gmail.com (for outgoing)


see link below for more information.
