In the past, I was able to create a network on my MacBook Pro, which was connected via firewire to an earlier SL mixer (16.2). Then I would connect to the network I created with an iPad Pro, and run the mixer from there. The router should not be needed, if you have a spare laptop to connect to the board. Not working for me now with a newer IPad and UC. Seems to be more of a network compatability issue between Mac/Sierra OS and IPad/Catalina OS. Also, be sure to select the network you have created, whether on your router or computer. Hope this helps.
