Am trying to create layout for a map book series (10,000 maps) but having problems with adding a legend. As soon as I add a legend to the layout the CPU maxes out at 100% and ArcGIS pro is unresponsive and I end up having to close it using task manager. I have tried this on several PCs at work but same problem.
Has anyone experienced this and what is the solution. I can use data driven pages fine in ArcMap 10.4 without any issues.
