I think it’s an issue with the android app on this one. I just tried (it’s a 2021 heated seats module) and got the same message on android version, but connects right away on windows version:
I believe I saw on the other forum you connected with an updated app.
I still couldn't connect with the Android app, but have the latest Windows version connected.
I can connect to drivers seat module and read the values,
Tested device: Heated Seat Module

but when I try to change, I get:
Failed. Security access denied.
My SGM bypass is working on the BCM OK.
Trying from the Comfort screen that has a long list of options:
I was able to get the heat setting to change, but vent refuses.
This is nuts.
It lets me make changes on the vent, but only using random - and + values and doesn't match the displayed results.
