Nice idea, but having problems – iOrnament: draw mandala & art Review

I used this app for the first time on my iPhone 8+. I pulled together a pretty mandala, although I would like a user guide to explain some of the features. But the real kicker is that it froze up on me several times when I was trying to save it. It appeared to be processing. And then it crashed on me several times while I worked on it. I could reopen the app and it would allow me to continue working, but that is a show stopper for me. I don’t want to put time and effort into a project and possibly lose my project when it crashes. I hope this is something you can look into and fix...???
