Sorry for the frustration @ozmadman. @Saddlesaur is correct, they are two completely separate apps. Wahoo X is just the name of the subscription that gives you access to both apps. If you are on SYSTM right now, you don’t really need to change anything there. If you want to explore RGT, then it will require downloading that app.
Of course, you can always contact our support team if you are stuck.
