I'm sorry you're having trouble with fill. Since releasing the latest version we've heard a number of complaints about the new build stalling/lagging during fill, so I have a couple of questions:
* Are you experiencing this with every drawing? Or is it just this one, or some, in particular? * Do you have work on your device that has not yet synced (work syncing in the background while you're working can slow drawing performance)? Please sign in with your Adobe ID to https://assets.adobe.com/cloud-documents and make sure that all of your work (including current edits on any drawing you're working on) shows up there. * Are you only having trouble with fill or is the app also stalling when you zoom/pan or do other transitions? * Which drawing tools are you using (Pixel, Live, or Vector)? Vector fill is an extremely complex action so it will help to know if you're using those tools.
