Edge Explore 2 with Venu 3S - No Physio TrueUp/Unified Training Status, No Effect on Body Battery?

Hi everyone, I recently purchased an Edge Explore 2 thinking that if I use my EE2 with my Venu 3S watch (I have this for a year), I could just sync all the normal data I would get from my Venu 3S such as body battery, recovery, etc.

But after using EE2 for the first time, I couldn't understand why it does not impact my body battery or even matching up the recovery status between the two devices. I've been hearing that Garmin has actually removed TrueUp from EE2? Is this true?

I'd love to get everyone's thought or advise on this, and whether there are any fix to get the data matched up and synced across these two devices? It is actually quite frustrating since I use the body battery a lot and don't want to over-exert myself after a long cyling tour.

Thanks!
