Excellent, I'll try it out soon. Thanks!
A fix has been implemented for this now.
Hi Mark - thanks for reporting this. We're aware of the issue and it's in our priority work queue to look at.
When undoing a route change, the map resets back to the previous view. As I make large routes, this often times means I have to zoom out, pan and zoom back in. I just want the changes undone, not my view.
