Yeah, I'm right in the middle of two stories so...
I had that issues as well - I write in manuscript format, so the first line was indented in every paragraph, spacing was 1.5, text was justified, and my font is Courier New. I found just copying it that way made the format impossible to edit, even in Firefox. You can't change the indents or justification and when it is posted, the text gets wonky and you can't use the app font options.
I had to change everything to align left in Word, then copy and paste into Firefox, then edit it from there. I'm still always cleaning up space issues between words, but it's the only way I've found it to work properly with the app.
And I was excited about the draft options, had some time and drafted six or seven episodes ahead, but then when I went to publish the schedule, I just got an error. Had to delete all of those and rewrite. LOL. It's all a hot mess.
