I created a point address locator in ArcGis Pro 2.9. I am able to use the locator tab to query for and find sub address locations using my locator. But when I try to use the LocatorTask to query for the same sub address locations, using the same single line input, I get no results. I have started trying to use multiple line inputs also, but so far no luck. I am using ArcGisRuntime 100.14 for this test.
I have no trouble finding standard addresses using the locator task, but I have not yet seen it return a subaddress location.
