Why doesn’t on-set distribution work?

• Please make sure that the Mac running Drylab Creator is connected to the same Wi-Fi network as the iPads and iPhones running Viewer. 
• Make sure that on-set distribution is enabled in Creator and in Admin, and that you (or your production owner) have paid for on-set distribution. 
• If neither of the above helps, check that your Wi-Fi network doesn’t block Bonjour, ZeroConf or multicast traffic.
