Bad new app - No back up for when writing reviews

I spend more than an hour writing a review using the IMDb app on my phone.I don't know what happen, but suddenly all I had written was vanished before I posted it. As an example, when you are writing something on Facebook and you hit the wrong button, when u find your way back to the post you were writing a comment on, you draft is still there and you can continue writing where you left off and post it. Not so here on IMDb. BIG IRRITATING FAIL 👎👎👎
