That is true that any drawing will be canceled if a two finger zoom or pan is detected. That's necessary though, at least when stylus mode is disabled, to prevent accidental drawing while trying to zoom. If you uncheck the option to allow touch input with stylus mode, then you'd never encounter that problem, so that's something to consider. I implemented a fix for a similar issue here (https://www.zubersoft.com/mobilesheets/f...11292.html) which may fix what you are experiencing though.
