Dont loose your time with this App

I, mean, dont loose your time with this app, literally.
I lost SEVERAL maps with more than 30 items.
A year ago, I installed it because I already had the desktop version. I had lost meetings with customers, an entire conference annotations.
Today, I decided to give them s second chance and reinstalled the new version of the app. And I, right now, lost more than 30 items that I put in a map about a book. They created many cool resources but couldnt care the basic. I cannot trust this app.
