Telemetry Viewer (android app)

I know it’s not really a GCS, but it’s the best way to display telemetry data for RC systems without Mavlink support. Is anyone able to get Flight mode displayed correctly in Telemetry Viewer? I think it might be related to Ardupilot.

I couldn’t get Ardupilot android app to display flight mode. The only success is with Frsky receiver. I also tested the SIYI system, ELRS, and Qczek LRS. All working fine in Telemetry Viewer except for the Flight mode status.
