We are experiencing a problem with ArcGIS Pro (2.8 but also with 2.7) in which adding a legend to a layout will cause the entire project to run extremely slowly. This seems to be exasperated by using the 'Only show features in the map extent' option but not exclusively which is making troubleshooting tricky.
Our data is predominately coming from an SDE, the rest being a random assortment of file GDB and shapefiles.
Clearing the caches and setting the display settings to their lowest doesn't help.
Any ideas or settings to try??
The specs are good and ArcPro runs just fine the rest of the time. It is only after adding the legend that it slows to a crawl.
