Apple Watch -> Strava: No “location data”

Got a new Apple Watch SE: Using the Workout app, I walked around the block to test set to “Outdoor Walk”, and finished it when I got back.

I open up Strava; the walk shows up as ready to be imported. Upon import, I get the popup saying there is no “location data” (screenshot below) and nothing shows up on my feed.

What gives? Apple Workout has been given permission in Settings to use Loc Services.
