“In order for AI FTP Detection to have enough data to accurately detect your FTP, you need a minimum of 10 completed TrainerRoad indoor workouts .”
Did you have a scheduled TR workout on your calendar that got associated with your TPV workout? There must be some connection to a TR workout for them to “count” in this instance.
You reference using TPV for your workouts, so you are doing the work inside. If you want to gain access to AI FTPD, why not simply bite the bullet and run the needed workouts in the TR app until the 10 workout requirement is met?
The easier workaround for me is to forget about AI FTP and use the intervals.icu value. Hopefully it will be fixed with proper outdoor workout support.
