As of yesterday, for me, if I do a workout and pick a route, I do the correct route, still get the correct route badge, but the title given by Zwift when saving the activity and then uploading to Strava is different. For example, did Shisa Shakedown yesterday, and Zwift title said on Snowman, although route image and badge were correct. Same thing today, doing Tempus Fugit and said it was on Queen’s Highway After Party, using workout mode. Then did free ride and route and route title matched.
I believe this has been reported already, something to do with how you can choose a different route from the workout screen, but it doesn’t carry over to your activity correctly.
Weird, I’ve just been getting “[workout name] in [world]” lately e.g. “HIIT Intervals in Yorkshire”
