"Timeout" mirroring iPad Pro to MacBook Pro

I’m trying to mirror my iPad Pro drawing app to my macbook pro, but all I’m getting is static and “Timeout”. Manycam knows the iPad is there, but the signal is no longer transmitting. I’m running Mac OS 10.15.7 (Catalina) and connect with a USBc doc that has USB ports. iPad is running 14.2 and Manycam is 7.7.1.2. I tried the beta as well (7.8.0.1), but had the same issue. Please help!

@tamraconteur Try to touch your iPad so the screen is on, then connect to it in ManyCam.
