I hope this is the right place for reporting issues with the new server. Anyway, Quick Draw isn't working. It's nearly impossible to get it to recognize that you're drawing the stroke in the correct place, and the one time I have gotten it, the green stroke looked glitchy.
Edit: After several restarts of stroke order hidden setting, it started working correctly. Then I changed to character disappears and it was glitchy again. I restarted the challenge and it worked fine.
It did, but after pausing and selecting restart (or whatever the wording is) it worked ok. I haven't worked with it since, I'll let you know if it has problems again tonight.
