Unfortunately, not all devices measure in the same way, and should be a great opportunity to create different bike, indoor/outdoor, TT or normal, or just target a *** number.

If you want to create a workout based in *******, VO2Max, TT bike, it's difficult to always translate to %FTP.

Being a FTP believer, to base everything in % of a number sometimes make to spend too much time or make mistakes when creating workouts.
