You can attach people to schedule items via the CSV import so that your attendees can see their profiles with a simple tap.
This article covers the basic import. A session can have several named lists of people, and the guide to lists on schedule items covers everything else you can do with them.
To add people to your schedule item:
Import the People using the CSV import and you must provide a "Unique ID" field, like it sounds must be different for each person you import.
Import your schedule or multitrack CSV, you can provide and map a "People IDs" column. The value of this column should be the person's Unique ID you provided with the people import. To attach multiple people, include more than one ID, separated by a comma.
A column headed People IDs fills the session's first people list (usually Speakers). If the session has no people list yet, Yapp creates one called Speakers.
Example with a sample of the Conference demo app
People page
Multi-Track page
Attaching multiple people to a session
To attach multiple people, include more than one ID, separated by a comma.
If you edit the file manually and don't use a spreadsheet application (like Excel or Google Sheets for example), you need to wrap the IDs using double quotes
You can verify that it is configured properly during the import process
