Historically, all Digital Retailing pages would be denoted with '/R-' in Google Analytics, following a consistent naming taxonomy and to make analysis quicker and easier. Unfortunately we cannot do this with GA4 since doing so strips out custom UTM and GCLID/DCLID parameters, which can greatly affect attribution. To prevent these issues from happening, we are not touching how Google populates this field in GA4 so now you will actually see the true page path.
When you open up the default Pages and Screens report, you will now see the actual Digital Retailing URL instead. There are some benefits to seeing the full URL vs the Digital Retailing page name, but if you want to see Digital Retailing pages how they have historically been, we do have an event parameter called 'roadster_page_name' which will give you this.
