Also an interesting workaround. I've tested it, but unfortunately it doesn't work for me either. 😔
Initially, I was still offered biometric unlocking from time to time. For a few days now, I've been asked to enter my password every time I change my profile.
I don't really want to replace my long password with a short PIN for the sake of convenience, even though it should probably still be very secure due to the throtteling. As I change profiles frequently, this is quite annoying in the long run...
