Long Time User: Apple Pencil support broken – Grafio 4 - Diagram Maker Review

I’ve been using this wonderful app since the first days of the iPad Air 2. I recently started using the App with the 2018 iPad with Apple Pencil support. The app was working flawlessly. However, after ios12 and the update the app is unusable with the Apple Pencil. 10 seconds after loading the app up the pencil becomes laggy and strokes don’t register, resulting in some funky letters. The last update did not alleviate the issue.
