So, I’d registered for the event via the website (not via companion app).
When I started Zwift, I saw that I was registered as “joining” the event in the top right of the landing page.
However, once actually on the road, I received no invitation to join the event. I saw a number of other riders, moving along the road with the blue turbos attached to their virtual bikes.
According to the chat, I was not the only person affected. See related post about the same thing https://forums.zwift.com/t/signed-up-for-tdz-but-couldnt-join/
Any obvious reason for this?
