No training effect in Garmin Connnect

I used Zwift with Kickr and Garmin HRM. I had my watch on (Fenix 6X Pro) but disconnected from my phone during the training. Activity was imported to Garmin Connect, there is heart rate shown, it got synchronized with my watch, I can see there is that training shown as last activity but there is no training effect / load neither in watch nor app. Is there a way to get the load data from somewhere now after all? Previously training effect / load data was added to Zwift activity after few minutes, but I had my watch connected to the phone. It shows no load today and 0h recovery time needed.

I don’t know if/where you can get the data you require, someone with more technical insight will be along I’m sure. But do you know that you can connect your Garmin account to the Zwift app? It means you don’t need your watch or phone on as Zwift sends it all to them. It also sends it to any of the other usual data collectors like strava, wahoo, training peaks etc. There is a list of linked sites on Zwift.com.

Yup, I’m using Zwift app on my phone and it uploads an activity to Garmin. The watch I’m just wearing most of the time 24/7, but I disconnected it quickly from my phone same day earlier when I didn’t want to be interrupted and didn’t connect it back. I guess that’s why I don’t have training effect, but I’m wandering if the data is stored somewhere and it’s possible to sync it now
