I gave the smart control a first try yesterday with my Gen3 Levo and my Pixel 6 Pro.
Got the same as many have been describing here 2.5 years ago. It just doesn't work reliably. It sets a a reasonable support level initially and then never changes it again. No matter if HR, milage or duration controlled.
Phone screen was on and at the stem, 10cm from the TCU. App excluded from any power manegment.
If I consider when this problem already had been reported I guess Spec just gave up on it, dind't they?
