How to rejoin an event

Good night, morning ,etc etc.
Someone con explain to me how to rejoin an event for example in the case of a social ride and you are back of the main peloton (bunch?) and you need to return with the peloton.

I suppose its necessary to leave the event without saving??? Or close the app in the PC and then login again?? I dont know really how.

You can rejoin a Meetup within 30 minutes of the start, or an organised Zwift event if they have the “late join” option set. If neither of these apply, then you can’t rejoin.

If it is possible to rejoin, then exit and save the ride, go back in to a free ride and the “Join Event” button should appear for you as before and you’ll be taken back in.
