Dear Computer Lady,
On my computer, I have my email set up so that I can see a list of messages on the side, and I can read an individual message in the main part of my screen.
On my iPad, I seem to have one screen that shows either my list of messages, or the message that I am reading, but not both.
Is there a way I can change this to show both?
I am going to guess that you are holding your iPad in an up and down position.
If you want to be able to view both the list of messages and the current message, just rotate the screen so that you are holding it horizontally. Doing that will automatically change the layout to include both the list and the message.
