I have setup a Event but I cannot see the member in that event when I sign-in on IPad. Also, when you try to schedule the event I get this text in red "This feature is being replaced. To schedule events you can now edit them directly from the entry details"
Can anyone help?
You need to go to the calendar view of the event and plan it from there. and you need to confirm it in the calendar
If you go into Admin > Tags > Channel > Tradeshow, you will see that the two Mobile Check-In statuses you have are Registered and Attended. All the leads in your screenshot have a status of Invited, not Registered, so they will not show up in the Check-In App.
