I posted the workaround on another thread. It's too long to re-type it here. The issue is Garmin Connect. I do the fix on the Garmin Connect app on my phone. The issue has nothing to do with the device.
I found the info. I posted here a while back. Good luck. I just recently created a bunch of new routes that have embedded segments. I use the workaround method and all of my segments are embedded in the routes correctly. I will be riding these routes next week. I already know they will work without even riding the route because I see the segment start/finish as purple flags on Garmin Connect.
With this workaround you don't need the GPS to be turned on. Leave the GPS off. The workaround is entirely done using your PC and your phone with the Garmin Connect app. Leaving your GPS on may have negative consequences on the workaround. Go to your Connect app on your phone, click 'more', click 'training and planning', click 'courses'. Select the route in question and delete it. Now go to your PC and open the Strava desktop website (I always use my PC to create routes), un-star the route, re-star the route. The route will show up on your Connect app on your phone in a few seconds. Open the route under the Connect app. The start/end of any embedded live segments will show up as purple flags on the map. If you don't see the purple flags then the live segments won't pop up. Looking at the map to find the purple flags is a good way to know if the segments are embedded without riding the route. Once the route looks good you could turn on the GPS and the updated route with the embedded segments will be downloaded to your GPS. There's a very small percentage of segments that will never be embedded even with the workaround, even when the segment is an uphill segment (Garmin blocks downhill live segments), for reasons unknown. I have reported this issue to Strava. I'm not betting on a timely fix, since the bigger problem has been going on for years without a permanent fix. Good luck.
