Maybe it’s just me, but it seems like the Zwift Academy filter in the Companion App is backwards.
Instead of making it easier to find ZA rides/races/workouts among the mass of other events going on, it hides the ZA events. Doesn’t seem like that would make much of a difference to someone trying to find a non-ZA ride, but, if it was the other way around, it would be useful for finding ZA events.
