Previously a marvel, now I’m utterly disappointed – Grafio 4 - Diagram Maker Review

I downloaded Grafio looking for an amazing app which could Help me do amazing things, and for Grafio 3 I had an incredible experience, everything ran smoothly, I did many amazing projects but this new update has been messing around all my previous and actual work. I spent almost 2 hours in a simple algorithm because the app kept moving the arrows all over the place and I wasn’t able to fix that until I worked around the app bugs. And in the end when I saved the project it just disappeared into a white canvas, there was no trace of my previous work I just spent hours working on. And there was NO way to take it back. I am so disappointed with this update because I really loved the app and now I’m forced to design the whole graph again and it keeps crashing.
