Ok did some further testing and I had an idea.
I figured this must be power related. So I found an inexpensive powered hub.

Lightning Hub -> USB Hub -> iRig Stream
The faint blue light became bright and I tested the recorder app and there was sound coming in no problem.
So a powered hub definitely helps when connecting it to a phone. It needs more power than the phone port can provide through a lightning adapter.
Another issue I found is when the iRig engages, it starts causing latency in the ethernet connection.
If I disconnect and reconnect the iRig from the powered hub, this goes away.
It almost seems like an OS issue. I noticed it happened with the recorder app also.
I disconnected the iRig and reconnected it to the powered hub, the latency went away and the audio still worked.
I would recommend support test an iPhone with a hub and ethernet connected to track down this issue.
