I had a start time for the Bologna TT this morning and was warming up in Watopia. There was no automatic event join and when I tried manually the button simply disappeared and I was stuck in Watopia without any way of making it to the start line.
Manually double check that you are running the latest version of Zwift. Otherwise, you won’t have the latest features (e.g., TT mode racing, leader fence, etc… )
I also was riding in Watopia and on ZC entered the A TT in Italy and had a start time. I never had any reminder to join. When I tried to go manually, the event was closed. I then jumped into the B race and immediately joined. Then all worked fine.
From what I can tell, all of the TT races today were yanked from the schedule. I suspect they are working on the bugs that were discovered yesterday
