Syncing between Edge 1040 and Epix Pro

It is annoying as I have the same setup.  I ended up getting and HRM-Pro as this also records the heart rate outside of activities and body battery so my daily heart rate chart is complete.

I just don’t get why only a summary of the bike activity is synced from Connect to the Epix Pro?

That’s the way it always was and Garmin did not change this since release.

The primary, central „device“ is Garmin Connect and not your watch. All summary and details are reviewed in Connect and not the device itself. The watch does only receive the needed data for metrics calculation as this is done on the set primary training device.  

The watch has practically unlimited storage for training data. It just seems stupid not to transfer HR and GPS from Connect to Primary Training Device. 

I have the Epix Pro and the 1040 and had to do the same thing with the Garmin heart rate strap which is a good product.  I would underscore Garmin development needs to get this fixed.  It’s ridiculous.  

It's great that things are collected and centralized to Garmin Connect. But it seems to me, that Garmin Connect put at lot of priority on one's primary device. Especially if you look at your overall training and health. 

I have an Epix and Edge 1040 Solar. I use the Garmin Connect app on my phone or a third party app (Intervals.icu or Training Peaks) to review training data.

I understand wanting to have updated training status like estimated VO2 max, FTP, thresholds, max HR (not max for an activity, max for the person) on the watch. But I don't understand why someone would use a tiny watch screen to review data from a particular cycling activity synched from the Edge. I would just pull out my phone. Can someone explain the use case?

Yes.  The broadcast heart rate from the Epix doesn't connect to the Garmin 1040 solar.  So as another user reported, the solution is to buy the Garmin heart rate strap which DOES connect to the Garmin 1040 solar.  

For me it's the overall picture that's interesting not the details. I see my training status is primarly based on my watch while it almost ignores my training with the edge. I use Epix Pro 2, Edge 1040 and Garmin Pro Plus Heartrate monitor.

used that combo (epix pro gen2) saturday, works fine, at least now ...
