Earlier today I discovered a short coming with creating a street address role locator in Pro 2.5.1 if the feature class contains true arcs. (See: ArcGIS Pro Create Locator fails (again/still) The Create Locator tool can't handle a true arc and will fail when they are present in the feature class. It's my understanding that the problem will be fixed in version release 2.6.
Full disclaimer: I'm going to let my old school flag fly freely here. I have never in my life created a true curve and I have no intention of ever doing so; I have never seen the point in them and have experienced problems with them in the past when it comes to geocoding. That said...
