A full click results in the same behavior; as soon as I move into a new lane, the signal turns itself off, rather than staying on until I execute an actual turn. It's frustrating. As I said before, having to monitor what it's doing and correcting it when it gets it wrong is more work than just operating the stalk manually as I have for 35 years. I fully understand that this will need to be automated due to FSD, but I don't see much reason to use it when driving manually unless it nearly always (i.e., better than 98% of the time) works.A key tip I learned from TMC is to hold the half-press momentarily (1/3 second?) rather than a fast tap (1/10 second?) which the car ignores -- or did 2022.44.25 change that? Are you doing a fast tap?
Another possible difference is whether nav is on.
Does a full click on the stalk make it stay as long as it used to, i.e. until manual cancellation or a clear turn? I expected so but didn't test this yet.
