Garmin 520 Plus Navigation with Strava Routes

Hi - I just updated from the Garmin Edge 500 to the 520 Plus, primarily so I could use the navigation feature. I decided to try Strava for route building and that worked pretty well for ease of use and importing into the Garmin. However, when I load the route and start riding I get the message “Off Course” even though I’m clearly on course. I can see the route on the Garmin as defined, and that I’m on the route, however I get the message “Off Course”.

Does anyone know what change I need to do to get navigation feature to work? Thank you.
