Might have to try a different app. I tried one when I first read about it here. Got several pages of info including the basics like my name, d.o.b. passport id, photo, document and country signing certificates, and a thing called Data Group Hashes. I've deleted the app as it try to keep only things I use regularly but I've kept the screenshots just in case I lose my passport while travelling - may come in helpful getting a replacement!
