Summary
I have a class C device running on an instance of TTS Cloud. Uplinks from device are using ADR SF12. I can see an option to set the RX2 downlink to SF12, but as this is a class C device I’m not using RX2.

In the End Device > Settings > Network Layer > Frequency Plan I have set SF12 for RX2, but in the Live Data view I still see the following

      "rx2_data_rate": {
        "lora": {
          "bandwidth": 125000,
          "spreading_factor": 9,
          "coding_rate": "4/5"
        }
      },

Is there a way I can confirm/alter the SF used for downlinks
