Active Calories from Edge 1040 not syncing?

My research to date:

Reported as working as intended prior to FW12.15

Confirmed by Garmin as an issue 9 months ago with update in mind but no action.

As usual there are users who have the problem and those who don't; confirmed by 2 users with same usage as mine only with Edge1040 and FR965, both UTS compatible and both syncing activity calories across the board.

I today confirmed using my Marq Gen 2 for an activity alongside my passive Fenix 7 that the activity calories from the Marq are synched to the the Fenix and GC. This confirms my expected behaviour and that of the majority of users it would seem from forum posts.

A simple solution for Garmin is if a device is recording an Activity then that takes precedence for HR/Calories, over any passive device??

That what I thought Garmin would be doing with the definition of primarily wearing and primarily training. And you are absolutely right, HR, power, etc. should come from the recording device. No need to distinguish then.

The more I look into this the more annoyed I am getting.  It is clear now that the OHR readings on the watch are way off and under reading when cycling indoors or outdoors.  Now I know that is a limitation of the optical sensor, and that is why I use my Edge 1040 with HRM Strap and/or Power Meter when on bike.  But the fact that the True Up between devices and Garmin Connect is using the HR measured on the watch to calculate daily calories rather than the accurate HR measured on the Edge 1040 with the HRM Strap or the Calories calculated from Work done using Power Meter is just crazy .  So it appears ever since my expensive purchase of the EPIX 2 Pro and Edge 1040 the daily readings for HR and Calories are just way off for days I have trained on bike.  

Another example was a hilly Gravel bike yesterday, 2 hour ride, approx calories recored on Edge activity - 1306 calories (1306kj work on power meter).   Watch Active calories - 600 calories!! 

The only solution currently is to remove watch when recording activity on Edge 1040.  BUT I did not pay £1000 for a watch that I would have to remove when going out on bike.   This needs to be resolved.

i have a fenix 7 and I use a 1040 with power meter and HR strap for cycling, what about starting the activity in both devices with the edge as primary training device? Or maybe at the end of the activity discarding it on fenix? Finally, it would be definitely better not wearing fenix while cycling?

Yeah dual recording with Epix is another possible workaround - if Garmin not going to resolve.

In summary, training status etc are all synced up correctly now under UTS.

BUT unless I record everything with the watch as an activity then I am not going to get a single source of truth for my fitness state (all day HR / Calories / Intensity Minutes) unless the Epix OHR reads accurately when in passive mode which in my in my experience it is not!!

But I already dual record indoor rides on Zwift and Garmin Edge to try and keep training metrics up to date on Garmin

Well it turns out I don't need to dual record on Edge while Zwifting after all !!!  There were two reasons I was dual recording on Edge :

(1) To keep Garmin Training Status up to date ... but I didn't realise this has already been resolved:

(2) To display Average HR/PWR/Cadence - something that should already be in Zwift ... but there is also a workaround for this now:

When Zwifting I don't record using any Garmin devices. Trainer and all sensors are linked to Zwift via my computer. The sync back to Garmin gives me all of the data I need.

But you lost the possibility of doing a HR based workout following your watch when on free ride on Zwift, Rouvy, etc …

So I lost the possibility of doing something I don't do.
