The old editor worked with tablets. Since the changes it has been impossible to upload posts or reply if you are using an iPad. If you can read this the problem of inability to reply has been fixed but it is still not possible for me to submit a story, whereas before this new editor I could use my iPad no problem.
You could try using a texteditor on your Ipad and then copy paste. Or switch to html for the time being. And if I remember correctly it is possible when creating a new post to choose for markdown.
Allthough I know this will not solve this problem with the iPad it could keep you blogging while the SteemIt team fixes it.
