No console messages with Yaapu telemetry on Radiomaster GX12

Running Yaapu 2.1.0-dev on a new Radiomaster GX12 with EdgeTx 2.11.0, 2.4Ghz ELRS, Arducopter 4.5.7, CSRF passthrough telemetry, CSRF set in the Yaapu config, 500Hz (maximum available for the GX12), 1:2 telemetry ratio. Everything works except no console messages.

Same vehicle, almost identical setup on a Radiomaster Pocket, everything works perfectly including console messages. The only difference on the Pocket is EdgeTx 2.10.1.

What would cause all of the telemerty EXCEPT console messages to work on the GX12?
