StagesPower sync issues with Xert

Most of my rides are on a Wahoo Kickr trainer. The power data syncs nicely with Xert. When I ride in real life on my bike with StagePower, I cannot figure out how to get that power data to load into Xert. My HR data shows up but not power, and this results in a 0 xss activity. Any suggestions?

To resolve missing strain scores for activities with no power, select the main menu, Home, Profile Settings, General tab and enable Heart Rated Derived Metrics.
If you know your resting and max HR enter them before saving.
This will parse any activities lacking power data and estimate XSS, Focus, Difficulty and more based on HR alone.

What type of device are you using to record your outdoor rides?

Continuing the discussion from StagesPower sync issues with Xert:

Thank you! I use a Stages power meter for rides in real life. Strava records the effort and it syncs with Garmin, Xert, etc.

Have you recorded rides on EBC or a Garmin device without issues?
Is the problem only when you record a ride using Strava?

Your instructions on the settings solved the issue. That updated my fitness signature with XSS values for all my rides. Thank you, problem solved!

I think that you now have data derived from your heart rate, not actual power data.
You need to find out why the stages power data is not coming through to Xert.
