I have a Samsung Galaxy pared with a Fenix 7 Pro Solar, when I create a custom workout with only 1 step of runner lunge and try to sync the sync screen says my watch is not compatible.
I believe there is something wrong with "Workout" as a step type. The only options should be Warm Up, Exercise, Recover, Rest, Cool Down, or Other.
I had no issues sending this workout to my watch with step type as exercise.
