First ride went off without a hitch, but I noticed one interface inconsistency:
I registered/entered the event days ago in the Companion App. Every time I looked at the event after initially joining, it indicated I was Joined.
However, when I logged into the Zwift App (mac) this morning prior to the start, the schedule listing DID NOT indicate that I had Joined the event (the listing was unadorned). I figured I’d see what happened in-game before bailing out. Once I was riding in world the “Join Event” button appeared as expected for an event.
Everything else seemed to work fine.
