Super frustrated - bad user experience

I usually dont write review, but if you are going to make an album maker app, please save the user progress. It took me half hour to configured the album, while I left my phone to upload the photos, the phone was locked. Once I unlocked the phone, the app lost all my progress and I have to restart again. Seriously, I just wasted my half hour for nothing. Please, it is really not hard to save the user progress.
