Wendilla, yes I have tried that and sometimes it does go in, but then logs out again. Jomlett, I just press the mail icon on the home page is that what you mean? Sorry I'm blonde! LOL!
I would visit or contact an Apple Store and make an appointment at the Genius Bar. Very helpful. I had a problem last week after updating my 3 year old ipad. Sorted within 15 mins and also more tips gained in understanding.
