I ended up doing a factory reset and it solved this issue. Lock and unlock now working properly in the app. It also fixed my plug and charge issue as well as allowing the Automatic Date and time. Very happy the reset solved all of these minor but annoying issues. All is good and I’m loving my 4S 😊
It is addressed in the manual
Securing seat belt for passenger seat
If the passenger seat is unoccupied, the belt tongue can be placed near the belt outlet on the B-pillar trim panel to avoid contact noise with the plastic slider A (Fig. 2).
Great build - looks fantastic!
Wondering if you could comment on cabin noise levels - especially tire and wind noise. I assume you did not option thermally & noise insulated glass?
