After this update, I lost all my notes – Microsoft PowerPoint Review

I had powerpoints saved on my iPad with notes in them that I’ve accessed lots of times. Today I went to study after the app updated and all my notes are gone. I went into the version history to see if I could restore something, but it says this is the only version. I worked hard to take those notes in class. Support hasn’t been helpful. All my notes are gone for good.
