Thank you to Garmin for fixing the numerous issues with the edge 520 with the 3.0 update, including the RWGPS issue.
One more thing please. Please make it possible to use the Strava Live segments WHILE following a course. the Strava segments are useless unless they work while following a course. Garmin was able to this with their "Garmin Segments" on the edge 810. Is is not safe to navigate the menus to stop the course, do the segment , then navigate more menus to get the course started again while going fast, on the road close to cars, or in group rides.
I don't know where else to get the developers attention so if you know where to post this please get their attention!
