This has happened to me so many times while composing a blog on my iPad. I will start a post and then need to check something or take a picture to add to the post, when I come back to Blogger, my earlier work will be gone! I need to post and add more later, I guess. I have left without posting a couple of times, because of my frustration. Why isnt there an auto save or a save button!
Okay, why is the save button only available after I click the Done button. That doesn't make any sense. Done should be ready to publish, not I need to come back to this. But, now I know where it is and can use it. Grrrrr.
