We working on a resolution for this with Edge devices and compatible wearables.
I own an Edge 830 and just got also the new Fenix 6.
It's very annoying that Garmin connect does not know to sync the information between the devices.
Horrible
+1 for this issue, this is the only reason I don’t buy a new fenix 6 yet. Please fix it Garmin! Thanks!

You say it should be easy but Physio TrueUp hasn't been working properly on the Edge 130, despite being an advertised feature, since it launched over a year and a half ago and still no sign of a fix. The wireless sync doesn't work and you have to resynchronise via a PC to get the recovery minutes to match up.
Also things like activity minutes don't synchronise if you use a chest band with the Edge. That means you can go on a 5 hour bike ride and not meet your activity target for the day according to your watch which is a bit ridiculous. The workaround here is to use your watch instead of the chest band.
I agree syncing across devices it would be a great feature for people who run and cycle though, if only Garmin could get it working.
