On a late join enabled group ride, if a rider gets dropped or wrong turned, and they want to rejoin using late join, do they have to completely exit zwift, and then restart the app? or is there an easier way?
Also, if they have to exit, does saving their ride upon exiting prohibit them from late joining?
I think you just have to backout to the menu screen then join again. You might have to join a world to actually get prompted to join again.
Saving does not prohibit you from late joining.
If the event has started, it will show up in the main menu as started if late join is enabled. You should click that event and join from the pop up.
There is no need to logoff or shut down Zwift to rejoin an ongoing event.
