Neat app but doesn’t save state reliably – Grafio 4 - Diagram Maker Review

I have enjoyed the ambition of the app, but it falls in terms of reliability of usage. When you make objects and then star to draw freehand curves successively, it loses many of those freehand curves. I’ve tried different things to see what might be the reason, but it’s unclear. Love the app and would rate it higher if it were reliable.
