New Zwifter can't join group rides or routes

I just joined and the app on my computer will not let me join group rides or routes! Can access workouts fine. Anyone else have this problem? how do I fix it?

Is it possible you were trying to join routes you don’t have access to as a new user?

Some routes are level-locked (silly nowadays I know.)

I suspect as a new user this can be confusing if you don’t ride up to those fences and see them; but when trying to join them from the main menu, getting a warning message might not be useful (granted I don’t actually know what it does now.)
