Currently, if you're looking for the Rest End Point URL for a feature service in ArcGIS Online, you need to navigate to the parent layer and then the sublayer to find each URL. For newbies, this can be a bit confusing, especially as the URL info and "Copy" button tend to be located down the page far enough that if you don't scroll, you won't see it. And if you only copy the parent layer URL, this won't get you the correct URL for your needs (i.e. pulldata in Survey123).
IDEA: Include sublayer URL's on the Parent page in the "Layers" section for rapid locating, viewing and copying as well as clarity around what each URL applies to. Move the Parent layer URL to above the Layers section to clearly delineate it from the other URL's options.
