To publish a survey on multiple channels at once, You must create a 'Feedback Kiosk' channel for each of the iPads. Meaning that you will have to create 10 kiosk channels if you wish to publish a survey on different 10 iPads. This way you can also view the results from each iPad individually. 

Step-by-Step Instructions: 

1. Go to the 'Channel Management' tab.

2. Create a 'Feedback Kiosk' channel for each one of your iPads


3. Create a survey and publish it to all of your newly created Feedback Kiosk channels in the 'channel selection' tab

4. Go to the channel management tab and click on each one of your newly created Feedback Kiosk channels to find the authorization code for each one


5. Download the Feedbackly iPad app on every iPad

6. Type in the authorization code of each of your Feedback Kiosk channels into the authorization code field of the splash screen

7. That's it! Your survey will now be live on every iPad
