apple watch 3 workout app uploads?

I was under the impression I would be able to replace my garmin forerunner with the series 3 watch given it is supposed to be such a great activity device. I found out today that using the workout app in cycling mode will not upload to strava. It will send a senseless message to strava saying I rode with the apple watch and the mileage, but does not include any data that is pertinent to keeping my cycling data online. The workout app itself has a wonderful amount of data, but just won't transfer or upload. So I guess my less than obvious question is is it possible to use the workout app and get the route map, calories, HR, speed, etc, etc data to strava or do I have to run the strava app which is garbage along with running the workout app at the same time?
