Notification Commands Not Working

Configuration
1

Hi,

I’m trying out Notification Commands but they don’t seem to be working.

I’m trying out the following on Developer Tools:

service: notify.mobile_app_tlmtiago
data:
  message: "Command_volume_level"
  data:
    media_stream: "ring_stream"
    command: 20

I get a green checkmark but the phone ringer volume stays the same.

Any ideas?
