Hello,
When a user creates an event in a closed group, this event does not appear in the group timeline for other group members. They first need to attend the event before the event appears in the group timeline.
Events created in closed groups appear as closed events (sounds logical ;-), maybe this is why.
You don't have this problem with events created in open groups (appearing as open events).
Thanks!
