The group chat stays open even after the activity ends, so you can continue the conversation, share event photos, or plan your next activity together. If you’re looking to reconnect with a specific person from a past activity, you have two options:
Go to the Chats tab and select Acquaintances. There, you'll find a list of people you’ve met at previous activities.
Go to the For You tab and tap on Completed to see all past activities you attended. Open the relevant activity to find the list of participants.
From there, you can start a private chat or invite them to your next activity.
