shelleb on "recover old revision offline on wordpress android app"

Hi all,
I'm praying someone can help me with this as I've just lost hours of work.

I'm using the WordPress app on my Samsung Galaxy Tab 2. Today started to type out a post on the app. I got as far as the title, tags and categories, and then I went outside and subsequently offline to continue. Whilst offline I typed up the entire body of the post (about 2 hours work, hence my despair).

I finished up, left the post open in the app, closed my tablet and headed home. I later went to finish the post and publish it. STILL offline, I opened my tablet and was connecting my bluetooth keyboard. As the keyboard had not yet connected, when I opened wordpress (still open on the post) the tablet keyboard was up on the screen. I pressed the back button to close it, and I guess there was a delay and I pressed the button again, which actually then closed the post and saved it. Unfortunately somewhere in amongst that I guess I bumped a button or something strange happened but my entire post's text disappeared. I noticed it disappear as I clicked the back button, then it exited the post and saved the now blank post.

I have been SCOURING the net for help to try and recover my post. It seems (but I hope I am mistaken) that there is no way to see saved revisions in the app? Since this entire thing was all done offline, I can not hope to recover anything from the online site. this was only ever a local draft.

Please please someone give me a miracle as I have just lost hours of work and I can't bear the thought of having to type up my whole post again, heck I can not even remember everything, so it will take me about another 2 hours to retype :'(

Is this something that I should be fearful of in future? is it better to type up all my posts somewhere else on my tablet and just copy paste them over? I can't believe there was no undo option or way to see my previous revisions, it is a major glitch in the app because it is far too easy for this to happen again.

Also, I am not sure what to select above re what version of wordpress I am using. The app is up to date and as far as I see it says version 5.5 which is not an option above so I am a bit confused.
