Did it spray windshield?I just went out and tested it and it's working fine for me. You need to keep your hand flat, which is more natural, not cupped. Works reliably every time for me. This is 2022 LR, but I doubt it's any different for any other Yoke-equipped Tesla.
I suspect the software is looking to detect all three buttons sensed at about the same time. With a cupped hand, you may miss one of the buttons.
