Can't save drafts in app

I recently changed phones, and on my new Android, with a new install of the app, I can no longer save drafts in the app. There used to be a cheesy work around for this, using the back button to get the prompt to save the draft to pop up. That doesn’t work now.

I used to create a post, and add a pic from my phone, save the draft, and then type the post on my desktop. Now, I have to type posts on my phone, which is sort of miserable when I have a lot to say.
