When a route is selected to Union St, the checkered flag goes to that street but the on screen graphics throw the purple line to Union Rd, one street east of the requested location.
I’m clutching at straws here, but I wonder if it’s related to Union St being in WME as “A3054 - Union St”. Could a search for “Union Street” (so not using the road suffix abbreviation, and omitting the “A3054 - “ prefix) cause things to go awry?
Could we add “Union St” as an alternate name, to see if this helps?
