Google Home App does not show fan speed and temperature settings for AC unit - google-smart-home

Question

I'm trying to add an AC Unit to Google Home via Google Smart Actions. I have the action configured and successfully linked my app server to the Google Home App.
I have been using the following guide from Google to develop my app server:
https://developers.google.com/assistant/smarthome/guides/acunit
In response to Google's action.devices.SYNC request I am providing the following response:
{
"requestId": "request-id-providing-by-google",
"payload": {
"agentUserId": "unique-user-id",
"devices": [

},

},
{
"speed_name": "speed_two",
"speed_values": [

}
]
},
{

"speed_values": [

},

"speed_values": [

],

}
]
},
{
"speed_name": "speed_five",
"speed_values": [
{
"speed_synonym": [

],
"lang": "en"
}
]
}
],
"ordered": true
},
"supportsFanSpeedPercent": false,
"availableThermostatModes": [
"off",
"heat",
"cool",
"fan-only",
"dry",
"on"
],
"thermostatTemperatureRange": {
"minThresholdCelsius": 18,
"maxThresholdCelsius": 30
},
"thermostatTemperatureUnit": "C"
}
}
]
}
}
And in response to Google's action.devices.QUERY request I am providing this response:
{
"requestId": "request-id-providing-by-google",
"payload": {
"devices": {
"device-id": {
"status": "SUCCESS",
"online": true,
"on": true,
"currentFanSpeedSetting": "speed-five",
"thermostatMode": "off",
"thermostatTemperatureAmbient": 25,
"thermostatTemperatureSetpoint": 20,
"thermostatHumidityAmbient": 100
}
}
}
}
As you can see, I have:
Specified that my AC unit supports the On / Off, fan speeds and temperature setting traits
Given the necessary attributes for the specified traits
Provided the current values for the device and related traits
However, when I view this device in the Google Home App it only presents an On / Off button and no controls for fan speed and temperature.
I have looked through all related logs on Google Cloud Logging and there are no errors reports.
I have reviewed these seemingly related issues on the topic but the responses and comments have not resolved the issue:
https://github.com/actions-on-google/smart-home-nodejs/issues/500
https://github.com/actions-on-google/smart-home-nodejs/issues/330
Am I missing some parameters or config for these controls to appear?
Update 07/11 - Useful response from #ToniCorinne pointing out that on the Google Home Smartphone app FanSpeed controls are not currently supported, see this link:
https://developers.google.com/assistant/smarthome/develop/touch-controls#google_home_app
Obviously this doesn't account for TemperatureSettings, so I've opened the following bug with Google which at time of writing has not been assigned:

Answer 1

FanSpeed is not currently a supported trait with touch controls in the Google Home app.
TemperatureSetting for an AC_Unit should have touch-controls, however. You could file an issue on the public issue tracker with your SYNC response and applicable information like the Google Home app version you're seeing this issue on for more help.
