From iPadOS 14, Apple has introduced new app privacy controls. The user has enhanced control over apps and the services to which they have access. Apps are required to gain user permission to access local network resources.
The Moku iPad app needs local network access to locate and operate the Moku:Lab.
If your iPad cannot locate your Moku:Lab, please ensure that access to the local network is enabled for "Moku". You can find this control on your iPad Settings -> Privacy -> Local Network
